Weyl Semimetallic Phase in High Pressure CrSb and Structural Compression Studies of its High Pressure Polymorphs
Carl Jonas Linnemann, Emma Ehrenreich-Petersen, Davide Ceresoli +4
In this study, high pressure synchrotron powder X-ray diffraction is used to investigate the compression of two high pressure polymorphs of \ce{CrSb2}. The first is the \ce{CuAl2}-…
THz Surface Modes and Electron-Phonon Coupling in BiSe(111)
Adrian Ruckhofer, Davide Campi, Martin Bremholm +5
We present a combined experimental and theoretical study of the surface vibrational modes of the topological insulator (TI) BiSe with particular emphasis on the low-energy…
Computational search for Dirac and Weyl nodes in -electon antiperovskites
Anna Pertsova, R. Matthias Geilhufe, Martin Bremholm +1
We present the result of an \textit{ab initio} search for new Dirac materials among inverse perovskites. Our investigation is focused on the less studied class of lanthanide antipe…
Novel single-layer vanadium sulphide phases
Fabian Arnold, Raluca-Maria Stan, Sanjoy K. Mahatha +15
VS2 is a challenging material to prepare stoichiometrically in the bulk, and the single layer has not been successfully isolated before now. Here we report the first realization of…
Nanoscale Surface Dynamics of BiTe(111): Observation of a Prominent Surface Acoustic Wave and the Role of van der Waals Interactions
Anton Tamtögl, Davide Campi, Martin Bremholm +8
We present a combined experimental and theoretical study of the surface vibrational modes of the topological insulator BiTe. Using high-resolution helium-3 spin-echo spectr…
A Helium-Surface Interaction Potential of BiTe(111) from Ultrahigh-Resolution Spin-Echo Measurements
Anton Tamtögl, Michael Pusterhofer, Martin Bremholm +7
We have determined an atom-surface interaction potential for the HeBiTe(111) system by analysing ultrahigh resolution measurements of selective adsorption resonances. Th…
