Emergence of radial Rashba spin-orbit fields in twisted van der Waals heterostructures
Tobias Frank, Paulo E. Faria Junior, Klaus Zollner +1
Rashba spin-orbit coupling is a quintessential spin interaction appearing in virtually any electronic heterostructure. Its paradigmatic spin texture in the momentum space forms a t…
Edge states in proximitized graphene ribbons and flakes in a perpendicular magnetic field: emergence of lone pseudohelical pairs and pure spin-current states
Yaroslav Zhumagulov, Tobias Frank, Jaroslav Fabian
We investigate the formation of edge states in graphene ribbons and flakes with proximity induced valley-Zeeman and Rashba spin-orbit couplings in the presence of a perpendicular m…
Landau levels in spin-orbit coupling proximitized graphene: bulk states
Tobias Frank, Jaroslav Fabian
We study the magnetic-field dependence of Landau levels in graphene proximitized by large spin-orbit coupling materials, such as transition-metal dichalcogenides or topological ins…
Quantum Anomalous Hall Effects in Graphene from Proximity-Induced Uniform and Staggered Spin-Orbit and Exchange Coupling
Petra Högl, Tobias Frank, Klaus Zollner +3
We investigate an effective model of proximity modified graphene (or symmetrylike materials) with broken time-reversal symmetry. We predict the appearance of quantum anomalous Hall…
Chiral Majorana fermions in graphene from proximity-induced superconductivity
Petra Högl, Tobias Frank, Denis Kochan +2
We present a detailed theoretical study of chiral topological superconductor phases in proximity-superconducting graphene systems based on an effective model inspired by DFT simula…
Many-body quantum Monte Carlo study of 2D materials: cohesion and band gap in single-layer phosphorene
Tobias Frank, Rene Derian, Kamil Tokar +3
Quantum Monte Carlo (QMC) is applied to obtain the fundamental (quasiparticle) electronic band gap, , of a semiconducting two-dimensional (2D) phosphorene whose optical and el…
