PT Symmetry, induced mechanical lasing and tunable force sensing in a coupled-mode optically levitated nanoparticle
Sandeep Sharma, A. Kani, M. Bhattacharya
We theoretically investigate PT symmetry, induced mechanical lasing and force sensing in an optically levitated nanoparticle with coupled oscillation modes. The coupling in the lev…
Optomechanics of optically-levitated particles: A tutorial and perspective
George Winstone, Alexey Grinin, Mishkat Bhattacharya +4
Optomechanics, the study of the mechanical interaction of light with matter, has proven to be a fruitful area of research that has yielded many notable achievements, including the…
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…
Direct measurement of atomic entanglement via cavity photon statistics
Nilakantha Meher, M. Bhattacharya, Anand K. Jha
We propose an experimental scheme for the measurement of entanglement between two two-level atoms. Our scheme requires one of the two entangled atoms to interact with a cavity fiel…
Injection locking of a levitated optomechanical oscillator for precision force sensing
Siamak Dadras, Robert M. Pettit, Danika R. Luntz-Martin +3
We report on the injection locking of an optically levitated nanomechanical oscillator (a silica nanosphere) to resonant intensity modulations of an external optical signal. We exp…
Single-photon transfer using levitated cavityless optomechanics
Pardeep Kumar, M. Bhattacharya
We theoretically explore a quantum memory using a single nanoparticle levitated in an optical dipole trap and subjected to feedback cooling. This protocol is realized by storing an…
