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…
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…
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…
Magnetometry via spin-mechanical coupling in levitated optomechanics
Pardeep Kumar, M. Bhattacharya
We analyze magnetometry using an optically levitated nanodiamond. We consider a configuration where a magnetic field gradient couples the mechanical oscillation of the diamond with…
Single and two-mode mechanical squeezing of an optically levitated nanodiamond via dressed-state coherence
Wenchao Ge, M. Bhattacharya
Nonclassical states of macroscopic objects are promising for ultrasensitive metrology as well as testing quantum mechanics. In this work, we investigate dissipative mechanical quan…
