Instabilities near ultrastrong coupling in microwave optomechanical cavity

Soumya Ranjan Das, Sourav Majumder, Sudhir Kumar Sahu +3

With artificially engineered systems, it is now possible to realize the coherent interaction rate, which can become comparable to the mode frequencies, a regime known as ultrastron…

Superconducting vortex-charge measurement using cavity electromechanics

Sudhir Kumar Sahu, Supriya Mandal, Sanat Ghosh +2

As the magnetic field penetrates the surface of a superconductor, it results in the formation of flux-vortices. It has been predicted that the flux-vortices will have a charged vor…
