Title	2D atomic mapping of oxidation states in transition metal oxides by scanning transmission electron microscopy and electron energy-loss spectroscopy			Type	A1 Journal article
Year	2011	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	107	Issue	10	Pages	107602
Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
Abstract	Using a combination of high-angle annular dark-field scanning transmission electron microscopy and atomically resolved electron energy-loss spectroscopy in an aberration-corrected transmission electron microscope we demonstrate the possibility of 2D atom by atom valence mapping in the mixed valence compound Mn3O4. The Mn L2,3 energy-loss near-edge structures from Mn2+ and Mn3+ cation sites are similar to those of MnO and Mn2O3 references. Comparison with simulations shows that even though a local interpretation is valid here, intermixing of the inelastic signal plays a significant role. This type of experiment should be applicable to challenging topics in materials science, such as the investigation of charge ordering or single atom column oxidation states in, e.g., dislocations.

Title	Anisotropic packing and one-dimensional fluctuations of C₆₀ molecules in carbon nanotubes			Type	A1 Journal article
Year	2005	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	95	Issue	18	Pages	185506-185506,4
Keywords	A1 Journal article; Condensed Matter Theory (CMT)
Abstract	The confinement of a C-60 molecule encapsulated in a cylindrical nanotube depends on the tube radius. In small tubes with radius R-T less than or similar to 7 A, a fivefold axis of the molecule coincides with the tube axis. The interaction between C-60 molecules in the nanotube is then described by a O-2-rotor model on a 1D liquid chain with coupling between orientational and displacive correlations. This coupling leads to chain contraction. The structure factor of the 1D liquid is derived. In tubes with a larger radius the molecular centers of mass are displaced off the tube axis. The distinction of two groups of peapods with on- and off-axis molecules suggests an explanation of the apparent splitting of A(g) modes of C-60 in nanotubes measured by resonant Raman scattering.

Title	Bulk magnetic order in a two-dimensional Ni¹⁺/Ni²⁺ (d⁹/d⁸) nickelate, isoelectronic with superconducting cuprates			Type	A1 Journal article
Year	2010	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	104	Issue	20	Pages	206403
Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
Abstract	The Ni(1+)/Ni(2+) states of nickelates have the identical (3d(9)/3d(8)) electronic configuration as Cu(2+)/Cu(3+) in the high temperature superconducting cuprates, and are expected to show interesting properties. An intriguing question is whether mimicking the electronic and structural features of cuprates would also result in superconductivity in nickelates. Here we report experimental evidence for a bulklike magnetic transition in La(4)Ni(3)O(8) at 105 K. Density functional theory calculations relate the transition to a spin density wave nesting instability of the Fermi surface.

Title	Casting light on the darkening of colors in historical paintings			Type	A1 Journal article
Year	2013	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	111	Issue	20	Pages	208302-208305
Keywords	A1 Journal article; Electron microscopy for materials research (EMAT); AXES (Antwerp X-ray Analysis, Electrochemistry and Speciation)
Abstract	The degradation of colors in historical paintings affects our cultural heritage in both museums and archeological sites. Despite intensive experimental studies, the origin of darkening of one of the most ancient pigments known to humankind, vermilion (α-HgS), remains unexplained. Here, by combining many-body theoretical spectroscopy and high-resolution microscopic x-ray diffraction, we clarify the composition of the damaged paint work and demonstrate possible physicochemical processes, induced by illumination and exposure to humidity and air, that cause photoactivation of the original pigment and the degradation of the secondary minerals. The results suggest a new path for the darkening process which was never considered by previous studies and prompt a critical examination of their findings.

Title	Ciliary white light : optical aspect of ultrashort laser ablation on transparent dielectrics			Type	A1 Journal article
Year	2013	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	110	Issue	9	Pages	097601-97605
Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
Abstract	We report on a novel nonlinear optical phenomenon, coined as ciliary white light, during laser ablation of transparent dielectrics. It is observed in 14 different transparent materials including glasses, crystals, and polymers. This phenomenon is also universal with respect to laser polarization, pulse duration, and focusing geometry. We interpret its formation in terms of the nonlinear diffraction of the laser generated white light by the ablation crater covered by nanostructures. It carries rich information on the damage profile and morphology dynamics of the ablated surface, providing a real time in situ observation of the laser ablation process.

Title	Coherent three-level mixing in an electronic quantum dot			Type	A1 Journal article
Year	2009	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	102	Issue	2	Pages	026808,1-026808,4
Keywords	A1 Journal article; Condensed Matter Theory (CMT)
Abstract	We observe magnetic-field-induced level mixing and quantum superposition phenomena between three approaching single-particle states in a quantum dot probed via the ground state of an adjacent quantum dot by single-electron resonant tunneling. The mixing is attributed to anisotropy and anharmonicity in realistic dot confining potentials. The pronounced anticrossing and transfer of strengths (both enhancement and suppression) between resonances can be understood with a simple coherent level mixing model. Superposition can lead to the formation of a dark state by complete cancellation of an otherwise strong resonance, an effect resembling coherent population trapping in a three-level-system of quantum and atom optics.

Title	Confinement effects on intermediate-state flux patterns in mesoscopic type-I superconductors			Type	A1 Journal article
Year	2009	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	103	Issue	26	Pages	267002,1-267002,4
Keywords	A1 Journal article; Condensed Matter Theory (CMT)
Abstract	Intermediate-state flux structures in mesoscopic type-I superconductors are studied within the Ginzburg-Landau theory. In addition to well-established tubular and laminar structures, the strong confinement leads to the formation of (i) a phase of singly quantized vortices, which is typical for type-II superconductors and (ii) a ring of a normal domain at equilibrium. The stability region and the formation process of these intermediate-state structures are strongly influenced by the geometry of the sample.

Volume	110	Issue	6	Pages	065501-65505
Keywords	A1 Journal article; Plasma Lab for Applications in Sustainability and Medicine – Antwerp (PLASMANT)
Abstract	Structural defects inevitably appear during the nucleation event that determines the structure and properties of single-walled carbon nanotubes. By combining ion bombardment experiments with atomistic simulations we reveal that ion bombardment in a suitable energy range allows these defects to be healed resulting in an enhanced nucleation of the carbon nanotube cap. The enhanced growth of the nanotube cap is explained by a nonthermal ion-induced graphene network restructuring mechanism.

Title	Diffusion of interacting particles in discrete geometries			Type	A1 Journal article
Year	2013	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	111	Issue	11	Pages	110601
Keywords	A1 Journal article; Condensed Matter Theory (CMT)
Abstract	We evaluate the self-diffusion and transport diffusion of interacting particles in a discrete geometry consisting of a linear chain of cavities, with interactions within a cavity described by a free-energy function. Exact analytical expressions are obtained in the absence of correlations, showing that the self-diffusion can exceed the transport diffusion if the free-energy function is concave. The effect of correlations is elucidated by comparison with numerical results. Quantitative agreement is obtained with recent experimental data for diffusion in a nanoporous zeolitic imidazolate framework material, ZIF-8.

Title	Discovery of a superhard iron tetraboride superconductor			Type	A1 Journal article
Year	2013	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	111	Issue	15	Pages	157002-157005
Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
Abstract	Single crystals of novel orthorhombic (space group Pnnm) iron tetraboride FeB4 were synthesized at pressures above 8 GPa and high temperatures. Magnetic susceptibility and heat capacity measurements demonstrate bulk superconductivity below 2.9 K. The putative isotope effect on the superconducting critical temperature and the analysis of specific heat data indicate that the superconductivity in FeB4 is likely phonon mediated, which is rare for Fe-based superconductors. The discovered iron tetraboride is highly incompressible and has the nanoindentation hardness of 62(5) GPa; thus, it opens a new class of highly desirable materials combining advanced mechanical properties and superconductivity.

Title	Efficient numerical approach to inhomogeneous superconductivity: the Chebyshev-Bogoliubov-de Gennes method			Type	A1 Journal article
Year	2010	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	105	Issue	16	Pages	167006,1-167006,4
Keywords	A1 Journal article; Condensed Matter Theory (CMT)
Abstract	We propose a highly efficient numerical method to describe inhomogeneous superconductivity by using the kernel polynomial method in order to calculate the Greens functions of a superconductor. Broken translational invariance of any type (impurities, surfaces, or magnetic fields) can be easily incorporated. We show that limitations due to system size can be easily circumvented and therefore this method opens the way for the study of scenarios and/or geometries that were unaccessible before. The proposed method is highly efficient and amenable to large scale parallel computation. Although we only use it in the context of superconductivity, it is applicable to other inhomogeneous mean-field theories.

Title	Electron-phonon bound states in graphene in a perpendicular magnetic field			Type	A1 Journal article
Year	2012	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	109	Issue	25	Pages	256602-256605
Keywords	A1 Journal article; Condensed Matter Theory (CMT)
Abstract	The spectrum of electron-phonon complexes in monolayer graphene is investigated in the presence of a perpendicular quantizing magnetic field. Despite the small electron-phonon coupling, usual perturbation theory is inapplicable for the calculation of the scattering amplitude near the threshold of optical phonon emission. Our findings, beyond perturbation theory, show that the true spectrum near the phonon-emission threshold is completely governed by new branches, corresponding to bound states of an electron and an optical phonon with a binding energy of the order of alpha omega(0), where alpha is the electron-phonon coupling and omega(0) the phonon energy.

Title	Experimental evidence for oxygen sublattice control in polar infinite layer SrCuO₂			Type	A1 Journal article
Year	2013	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	111	Issue	9	Pages	096102-96105
Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
Abstract	A recent theoretical study [ Phys. Rev. B 85 121411(R) (2012)] predicted a thickness limit below which ideal polar cuprates turn nonpolar driven by the associated electrostatic instability. Here we demonstrate this possibility by inducing a structural transformation from the bulk planar to chainlike structure upon reducing the SrCuO2 repeat thickness in SrCuO2/SrTiO3 superlattices with unit-cell precision. Our results, based on structural investigation by x-ray diffraction and high resolution scanning transmission electron microscopy, demonstrate that the oxygen sublattice can essentially be built by design. In addition, the electronic structure of the chainlike structure, as studied by x-ray absorption spectroscopy, shows the signature for preferential hole occupation in the Cu 3d3z2-r2 orbital, which is different from the planar case.

Title	Experimental observation of single-file water filling of thin single-wall carbon nanotubes down to chiral index (5,3)			Type	A1 Journal article
Year	2010	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	104	Issue	20	Pages	207401,1-207401,4
Keywords	A1 Journal article; Particle Physics Group; Nanostructured and organic optical and electronic materials (NANOrOPT); Condensed Matter Theory (CMT)
Abstract	Single-file transport of water into carbon nanotubes is experimentally demonstrated for the first time through the splitting of the radial breathing mode (RBM) vibration in Raman spectra of bile salt solubilized tubes when both empty (closed) and water-filled (open-ended) tubes are present. D2O filling is observed for a wide range of diameters, d, down to very thin tubes [e.g., (5,3) tube, d=0.548 nm] for which only a single water molecule fits in the cross section of the internal nanotube channel. The shift in RBM frequency upon filling is found to display a very complex dependence on nanotube diameter and chirality, in support of a different yet well-defined ordering and orientation of water molecules at room temperature. Large shifts of the electronic transitions are also observed.

Title	Exploiting lens aberrations to create electron-vortex beams			Type	A1 Journal article
Year	2013	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	111	Issue	6	Pages	064801-64805
Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
Abstract	A model for a new electron-vortex beam production method is proposed and experimentally demonstrated. The technique calls on the controlled manipulation of the degrees of freedom of the lens aberrations to achieve a helical phase front. These degrees of freedom are accessible by using the corrector lenses of a transmission electron microscope. The vortex beam is produced through a particular alignment of these lenses into a specifically designed astigmatic state and applying an annular aperture in the condenser plane. Experimental results are found to be in good agreement with simulations.

Title	Extended Ginzburg-Landau formalism for two-band superconductors			Type	A1 Journal article
Year	2011	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	106	Issue	4	Pages	047005-047005,4
Keywords	A1 Journal article; Condensed Matter Theory (CMT)
Abstract	Recent observation of unusual vortex patterns in MgB2 single crystals raised speculations about possible type-1.5 superconductivity in two-band materials, mixing the properties of both type-I and type-II superconductors. However, the strict application of the standard two-band Ginzburg-Landau (GL) theory results in simply proportional order parameters of the two bandsand does not support the type-1.5 behavior. Here we derive the extended GL formalism (accounting all terms of the next order over the small τ=1-T/Tc parameter) for a two-band clean s-wave superconductor and show that the two condensates generally have different spatial scales, with the difference disappearing only in the limit T→Tc. The extended version of the two-band GL formalism improves the validity of GL theory below Tc and suggests revisiting the earlier calculations based on the standard model.

Title	Formation of multiple-flux-quantum vortices in mesoscopic superconductors from simulations of calorimetric, magnetic, and transport properties			Type	A1 Journal article
Year	2011	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	107	Issue	5	Pages	057002,1-057002,4
Keywords	A1 Journal article; Condensed Matter Theory (CMT)
Abstract	Because of strong flux confinement in mesoscopic superconductors, a giant vortex may appear in the ground state of the system in an applied magnetic field. This multiquanta vortex can then split into individual vortices (and vice versa) as a function of, e.g., applied current, magnetic field, or temperature. Here we show that such transitions can be identified by calorimetry, as the formation or splitting of a giant vortex results in a clear jump in measured heat capacity versus external drive. We attribute this phenomenon to an abrupt change in the density of states of the quasiparticle excitations in the vortex core(s), and further link it to a sharp change of the magnetic susceptibility at the transitionproving that the formation of a giant vortex can also be detected by magnetometry.

Title	Formation of stripelike flux patterns obtained by freezing kinematic vortices in a superconducting Pb film			Type	A1 Journal article
Year	2010	Publication	Physical review letters	Abbreviated Journal	Phys Rev Lett
Volume	104	Issue	1	Pages
Keywords	A1 Journal article; Condensed Matter Theory (CMT)
Abstract	We demonstrate experimentally and theoretically that the dissipative state of superconducting samples with a periodic array of holes at high current densities consists of flux rivers resulting from a short-range attractive interaction between vortices. This dynamically induced vortex-vortex attraction results from the migration of quasiparticles out of the vortex core (kinematic vortices). We have directly visualized the formation of vortex chains by scanning Hall probe microscopy after freezing the dynamic state by a field cooling procedure at a constant bias current. Similar experiments carried out in a sample without holes show no hint of flux river formation. We shed light on this nonequilibrium phenomena modeled by time-dependent Ginzburg-Landau simulations.
