Bulk-boundary correspondence in extended trimer Su-Schrieffer-Heeger model
Sonu Verma, Tarun Kanti Ghosh
We consider an extended trimer Su-Schrieffer-Heeger (SSH) tight-binding Hamiltonian keeping up to next-nearest-neighbor (NNN) hopping terms and on-site potential energy. The Bloch…

Polarization and third-order Hall effect in III-V semiconductor heterojunctions
Ojasvi Pal, Tarun Kanti Ghosh
We study Berry connection polarizability (BCP) induced electric polarization and third-order Hall (TOH) effect in a two-dimensional electron/hole gas (2DEG/2DHG) with Rashba-Dresse…
