Insulator-metal quantum phase transition in heavy topological insulators
Shouvik Sur, Pallab Goswami
Exponentially localized surface states are the most distinctive property of a crystal with non-trivial band topology. Such surface states play a key role in characterizing topologi…

Interaction-driven quantum anomalous Hall insulator in Dirac semimetal
Hongyu Lu, Shouvik Sur, Shou-Shu Gong +1
The interaction-driven quantum anomalous Hall (QAH) insulator has been sought for a long time in a Dirac semimetal with linear band touching points at the Fermi level. By combining…

Non-Abelian Stokes theorem and quantized Berry flux
Alexander C. Tyner, Shouvik Sur, Qunfei Zhou +4
Band topology of anomalous quantum Hall insulators can be precisely addressed by computing Chern numbers of constituent non-degenerate bands that describe quantized, Abelian Berry…
