Time reversal symmetry broken quantum spin hall effect in pseudospin-1 Dirac-Rashba system
Puspita Parui, Bheema Lingam Chittari
The Quantum spin Hall (QSH) phase is conventionally understood to be protected by time-reversal symmetry (TRS). Here, we theoretically investigated the fate of the QSH phase in a p…

Valley-polarized Quantum Anomalous Hall and Topological Metal Phase in Rashba induced pseudospin-1 lattice
Puspita Parui, Bheema Lingam Chittari
We study the topological properties of Rashba spin-orbit coupling and exchange coupling induced pseudospin- system Dice lattice under the influence of a staggered electric poten…
