Evidence for Multiband Superconductivity in 2H-NbSeS
K. Yadav, M. Lamba K. Bhattacharya, M. Majumder +1
The nature of superconductivity in 2H-NbSe2 has generated sustained debate in the recent past. While angle resolved photoemission spectroscopy data have been interpreted as evidenc…

Topological sensing of superfluid rotation using non-Hermitian optical dimers
Aritra Ghosh, Nilamoni Daloi, M. Bhattacharya
We theoretically investigate a non-Hermitian optical dimer whose parameters are renormalized by dispersive and dissipative backaction from the coupling of the passive cavity with a…

Atomic-superfluid heat engines controlled by twisted light
Aritra Ghosh, Nilamoni Daloi, M. Bhattacharya
We theoretically propose a quantum heat engine using a setup consisting of a ring-trapped Bose-Einstein condensate placed in a Fabry-Pérot cavity where the optical field carries o…
