Local phase-space Berry curvature and Hall transport in textured twisted bilayer graphene
Tohid Farajollahpour
Slow twist-angle and heterostrain textures in twisted bilayer graphene provide a natural route to phase-space Berry geometry. We show that a purely geometric tetrad/shift sector do…
Parity-driven RKKY decoupling and anomalous Dzyaloshinskii-Moriya interaction in -wave magnets
Morteza Salehi, Tohid Farajollahpour
Unconventional -wave magnets, characterized by an odd-parity momentum-dependent spin splitting, offer a fundamentally distinct paradigm for non-collinear spintronics. Here, we t…
Light-induced charge and spin Hall currents in materials with symmetry
Tohid Farajollahpour, R. Ganesh, Kirill Samokhin
Berry curvature, a momentum space property, can manifest itself in current responses. The well-known anomalous Hall effect in time-reversal-breaking systems arises from a Berry cur…
Synthetic non-Abelian gauge fields and gravitomagnetic effects in tilted Dirac cone systems
Tohid Farajollahpour, S. A. Jafari
In planar tilted Dirac cone systems, the tilt parameter can be made space-dependent by either a perpendicular displacement field, or by chemical substitution in certain systems. We…
The borophene sheet: A solid-state platform for space-time engineering
Tohid Farajollahpour, Zahra Faraei, S. A. Jafari
We construct the most generic Hamiltonian of the structure of borophene sheet in presence of spin-orbit, as well as background electric and magnetic fields. In addition to…
The role of the strain induced population imbalance in Valley polarization of graphene: Berry curvature perspective
Tohid Farajollahpour, Arash Phirouznia
Real magnetic and lattice deformation gauge fields have been investigated in honeycomb lattice of graphene. The coexistence of these two gauges will induce a gap difference between…
