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…
A Loop-Shaping Approach to Coherent Feedback Control in Cavity Optomechanical Cooling
Aoi Fujimoto, Hiroyuki Ichihara, Rina Kanamoto
We present a loop-shaping approach to coherent feedback (CF) control. By formulating the coupling between a quantum system and its environment in terms of the noise power spectrum,…
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…
Sensing atomic superfluid rotation beyond the standard quantum limit
Rahul Gupta, Pardeep Kumar, Rina Kanamoto +2
Atomic superfluids formed using Bose-Einstein condensates (BECs) in a ring trap are currently being investigated in the context of superfluid hydrodynamics, quantum sensing and mat…
Speed Limit of Efficient Cavity-Mediated Adiabatic Transfer
Akinori Suenaga, Takeru Utsugi, Rui Asaoka +3
Cavity-mediated adiabatic transfer (CMAT) is a robust way to perform a two-qubit gate between trapped atoms inside an optical cavity. In the previous study by Goto and Ichimura [H.…
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…
