Valley switch in a graphene superlattice due to pseudo-Andreev reflection
C. W. J. Beenakker, N. V. Gnezdilov, E. Dresselhaus +4
Dirac electrons in graphene have a valley degree of freedom that is being explored as a carrier of information. In that context of "valleytronics" one seeks to coherently manipulat…
Phase shift of cyclotron orbits at type-I and type-II multi-Weyl nodes
M. Breitkreiz, N. Bovenzi, J. Tworzydlo
Quantum oscillations of response functions in high magnetic fields tend to reveal some of the most interesting properties of metals. In particular, the oscillation phase shift is s…
Majorana quasiparticles of inhomogeneous Rashba chain
M. M. Maska, A. Gorczyca-Goraj, J. Tworzydlo +1
We investigate the inhomogeneous Rashba chain coupled to a superconducting substrate, hosting the Majorana quasiparticles near its edges. We discuss its subgap spectrum and study h…
Disorder and magnetic-field induced breakdown of helical edge conduction in an inverted electron-hole bilayer
D. I. Pikulin, T. Hyart, Shuo Mi +3
We calculate the conductance of a two-dimensional bilayer with inverted electron-hole bands, to study the sensitivity of the quantum spin Hall insulator (with helical edge conducti…
Quantum phase transitions of a disordered antiferromagnetic topological insulator
P. Baireuther, J. M. Edge, I. C. Fulga +2
We study the effect of electrostatic disorder on the conductivity of a three-dimensional antiferromagnetic insulator (a stack of quantum anomalous Hall layers with staggered magnet…
Metal--topological-insulator transition in the quantum kicked rotator with Z2 symmetry
E. P. L. van Nieuwenburg, J. M. Edge, J. P. Dahlhaus +2
The quantum kicked rotator is a periodically driven dynamical system with a metal-insulator transition. We extend the model so that it includes phase transitions between a metal an…
