Angular momentum of vortex-core Majorana zero modes
Giulia Venditti, Christophe Berthod, Louk Rademaker
Majorana zero modes (MZMs) are highly sought-after states with a possible application in quantum computation. Here, we show that vortex-core MZMs can carry a nontrivial angular mom…
Universal low-density power laws of the dc conductivity and Hall constant in the self-consistent Born approximation
Giacomo Morpurgo, Christophe Berthod, Thierry Giamarchi
The dc conductivity tensor of two-dimensional one-band metals with weak pointlike disorder and magnetic field is studied in the self-consistent Born approximation, with special emp…
Role of a higher dimensional interaction in stabilizing charge density waves in quasi-1D NbSe revealed by angle-resolved photoemission spectroscopy
Christopher W. Nicholson, Eike F. Schwier, Kenya Shimada +4
We revisit charge density wave (CDW) behavior in the archetypal quasi-one-dimensional (quasi-1D) material NbSe by high-resolution angle-resolved photoemission spectroscopy meas…
First direct observation of the Van Hove singularity in the tunneling spectra of cuprates
A. Piriou, N. Jenkins, C. Berthod +2
In two-dimensional lattices the electronic levels are unevenly spaced, and the density of states (DOS) displays a logarithmic divergence known as the Van Hove singularity (VHS). Th…
Schottky barrier heights at polar metal/semiconductor interfaces
C. Berthod, N. Binggeli, A. Baldereschi
Using a first-principle pseudopotential approach, we have investigated the Schottky barrier heights of abrupt Al/Ge, Al/GaAs, Al/AlAs, and Al/ZnSe (100) junctions, and their depend…
Modeling scanning tunneling spectra of
B. W. Hoogenboom, C. Berthod, M. Peter +2
Recent angle-resolved photoemission and neutron scattering data have provided new ingredients for the interpretation of scanning tunneling spectra on BiSrCaCuO.…
