Time-Reversal Symmetry Breaking in Re-Based Superconductors

To trace the origin of time-reversal symmetry breaking (TRSB) in Re-based superconductors, we performed comparative muon-spin rotation and relaxation (mu SR) studies of superconducting noncentrosymmetric Re0.82Nb0.18 (T-c = 8.8 K) and centrosymmetric Re (T ...

Magnetic exchange parameters and anisotropy of the quasi-two-dimensional antiferromagnet NiPS3

Diane Virginie Marie Lançon

Neutron inelastic scattering has been used to measure the magnetic excitations in powdered NiPS3, a quasitwo-dimensional antiferromagnet with spin S = 1 on a honeycomb lattice. The spectra show clear, dispersive magnons with a similar to 7 meV gap at the B ...

Spin-resolved band structure of a densely packed Pb monolayer on Si(111)

Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli

Monolayer structures of Pb on Si(111) attracted recently considerable interest as superconductivity was found in these truly two-dimensional (2D) structures. In this study, we analyzed the electronic surface band structure of the so-called striped incommen ...

Redox Levels through Constant Fermi-Level ab Initio Molecular Dynamics

Alfredo Pasquarello, Assil Bouzid

We develop a method to determine redox levels of half reactions through the use of ab initio molecular dynamics evolving at constant Fermi energy. This scheme models the effect of an electrode by controlling the charge transfer between the single-particle ...

Identification of Semiconductor Defects through Constant-Fermi-Level Ab Initio Molecular Dynamics: Application to GaAs

Alfredo Pasquarello, Assil Bouzid

We show that constant-Fermi-level ab initio molecular dynamics can be used as a computer-based tool to reveal and control relevant defects in semiconductor materials. In this scheme, the Fermi level can be set at any position within the band gap during the ...

Fermi-level pinning and intrinsic surface states of Al1-xInxNd(10(1)over-bar0) surfaces

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté

The electronic structure of Al1-xInxNd(10 (1) over bar0) surfaces is investigated by cross-sectional scanning tunneling spectroscopy and density functional theory calculations. The surface exhibits empty Al and/or In-derived dangling bond states, which are ...

High-energy electronic interaction in the 3d band of high-temperature iron-based superconductors

Maryna Viazovska, Helmuth Berger

One of the most unique and robust experimental facts about iron-based superconductors is the renormalization of the electronic band dispersion by factor of 3 and more near the Fermi level. Obviously related to the electron pairing, this prominent deviation ...

Nanoscale structural oscillations in perovskite oxides induced by oxygen evolution

Vasiliki Tileli

Understanding the interaction between water and oxides is critical for many technological applications, including energy storage, surface wetting/self-cleaning, photocatalysis and sensors. Here, we report observations of strong structural oscillations of B ...
