Emergence of a weak topological insulator from the BiSe family and the observation of weak anti-localization
Kunjalata Majhi, Koushik Pal, Himanshu Lohani +7
The discovery of strong topological insulators led to enormous activity in condensed matter physics and the discovery of new types of topological materials. Bisumth based chalcogen…

Pressure-induced phase transition in BiSe at 3 GPa: electronic topological transition or not?
Achintya Bera, Koushik Pal, D V S Muthu +2
In recent years, a low pressure transition around P 3 GPa exhibited by the AB-type 3D topological insulators is attributed to an electronic topological transition (E…

Sharp Raman Anomalies and Broken Adiabaticity at a Pressure Induced Transition from Band to Topological Insulator in Sb2Se3
Achintya Bera, Koushik Pal, D. V. S. Muthu +4
The nontrivial electronic topology of a topological insulator is thus far known to display signatures in a robust metallic state at the surface. Here, we establish vibrational anom…
