Spinor condensate persistent currents in an atomtronic Josephson necklace
Sayan Chatterjee, Nalinikanta Pradhan, Rina Kanamoto +2
The investigation of superflow in multi-junction Josephson circuits is currently a leading frontier of physics research, probing the fundamental manifestations of macroscopic phase…
Proposals for realizing a Josephson diode in Atomtronic circuits
Nalinikanta Pradhan, Rina Kanamoto, M. Bhattacharya +1
The Josephson diode, a non-reciprocal quantum element analogous to the familiar semiconductor p-n junction diode, has been realized in solid-state systems but remains unexplored in…
Fractional Shapiro steps in a Cavity-Coupled Josephson ring condensate
Nalinikanta Pradhan, Rina Kanamoto, M. Bhattacharya +1
The Josephson effect presents a fundamental example of macroscopic quantum coherence as well as a crucial enabler for metrology (e.g. voltage standard), sensing (e.g. Superconducti…
Signature of Andreev-Bashkin superfluid drag from Cavity Optomechanics
Nalinikanta Pradhan, Rina Kanamoto, M. Bhattacharya +1
The Andreev-Bashkin (AB) effect, corresponding to the dissipationless dragging of one superfluid by another, was predicted almost fifty years ago but has so far eluded experimental…
Ring Bose-Einstein condensate in a cavity: Chirality Detection and Rotation Sensing
Nalinikanta Pradhan, Pardeep Kumar, Rina Kanamoto +3
Recently, a method has been proposed to detect the rotation of a ring Bose-Einstein condensate, in situ, in real-time and with minimal destruction, using a cavity driven with optic…
Cavity optomechanical detection of persistent currents and solitons in a bosonic ring condensate
Nalinikanta Pradhan, Pardeep Kumar, Rina Kanamoto +3
We present numerical simulations of the cavity optomechanical detection of persistent currents and bright solitons in an atomic Bose-Einstein condensate confined in a ring trap. Th…
