Half unit cell shift defect induced helical states in Fe-based chalcogenide superconductors
Tamoghna Barik, Jay D. Sau
Recent scanning tunneling spectroscopy along crystalline domain-walls associated with a half unit cell shift have revealed sub-gap density of states that are expected to arise from…

On the signatures of non-topological patches on the surface of topological insulators
Tamoghna Barik, Jay D. Sau
The non-trivial topology in the layered (FTS) superconductor has been suggested by both theory and experiment to be strongly dependent on the T…

Non-equilibrium nature of non-linear optical response: Application to the bulk photo voltaic effect
Tamoghna Barik, Jay D. Sau
The bulk photovoltaic effect is an example of a non-linear optical response that leads to a DC current that is relevant for photo-voltaic applications. In this work, we theoretical…
