Chiral Anomaly Trapped in Weyl Metals: Nonequilibrium Valley Polarization at Zero Magnetic Field
Pablo M. Perez-Piskunow, Nicandro Bovenzi, Anton R. Akhmerov +1
In Weyl semimetals the application of parallel electric and magnetic fields leads to valley polarization -- an occupation disbalance of valleys of opposite chirality -- a direct co…
Hinge Spin Polarization in Magnetic Topological Insulators Revealed by Resistance Switch
Pablo M. Perez-Piskunow, Stephan Roche
We report on the possibility to detect hinge spin polarization in magnetic topological insulators by resistance measurements. By implementing a three-dimensional model of magnetic…
Hybrid kernel polynomial method
Muhammad Irfan, Sathish R. Kuppuswamy, Daniel Varjas +4
The kernel polynomial method allows to sample overall spectral properties of a quantum system, while sparse diagonalization provides accurate information about a few important stat…
Computation of topological phase diagram of disordered PbSnTe using the kernel polynomial method
Daniel Varjas, Michel Fruchart, Anton R. Akhmerov +1
We present an algorithm to determine topological invariants of inhomogeneous systems, such as alloys, disordered crystals, or amorphous systems. Based on the kernel polynomial meth…
Floquet interface states in illuminated three-dimensional topological insulators
H. L. Calvo, L. E. F. Foa Torres, P. M. Perez-Piskunow +2
Recent experiments showed that the surface of a three dimensional topological insulator develops gaps in the Floquet-Bloch band spectrum when illuminated with a circularly polarize…
Non-perturbative laser effects on the electrical properties of graphene nanoribbons
Hernan L. Calvo, Pablo M. Perez-Piskunow, Horacio M. Pastawski +2
The use of Floquet theory combined with a realistic description of the electronic structure of illuminated graphene and graphene nanoribbons is developed to assess the emergence of…
