Topological Fermi-arc surface resonances in bcc iron
Daniel Gosálbez-Martínez, Gabriel Autès, Oleg V. Yazyev
The topological classification of matter has been extended to include semimetallic phases characterized by the presence of topologically protected band degeneracies. In Weyl semime…
Trivial topological phase of CaAgP and the topological nodal-line transition in CaAg(P1-xAsx)
N. Xu, Y. T. Qian, Q. S. Wu +14
By performing angle-resolved photoemission spectroscopy and first-principles calculations, we address the topological phase of CaAgP and investigate the topological phase transitio…
Enhanced ultrafast relaxation rate in the Weyl semimetal phase of measured by time-and angle-resolved photoelectron spectroscopy
A. Crepaldi, G. Autès, G. Gatti +18
has recently been shown to realize in its low-temperature phase the type-II Weyl semimetal (WSM). We investigated by time- and angle- resolved photoelectron spect…
Z2Pack: Numerical Implementation of Hybrid Wannier Centers for Identifying Topological Materials
Dominik Gresch, Gabriel Autès, Oleg V. Yazyev +4
The intense theoretical and experimental interest in topological insulators and semimetals has established band structure topology as a fundamental material property. Consequently,…
BiTeCl and BiTeBr: a comparative high-pressure optical study
I. Crassee, F. Borondics, M. K. Tran +8
We here report a detailed high-pressure infrared transmission study of BiTeCl and BiTeBr. We follow the evolution of two band transitions: the optical excitation between two Ra…
Evidence for a Strong Topological Insulator Phase in
G. Manzoni, L. Gragnaniello, G. Autès +16
The complex electronic properties of have recently stimulated in-depth investigations that assigned this material to either a topological insulator or a 3D Dirac…
