Quantum Control of Heat Current
Gobinda Chakraborty, Subhadeep Chakraborty, Tanmoy Basu +1
We investigate the local thermal transport in a quantum trimer of harmonic oscillators connected to two thermal baths. The coupling between them are augmented by complex phases whi…
Quantum synchronization and correlation in bidirectionally and unidirectionally coupled optomechanical oscillators
Subhadeep Chakraborty, Amarendra K. Sarma
Optically coupled optomechanical oscillators has turned out to be a versatile experimental resource for exploring optomechanical synchronizations and correlations. In this work, we…
Delayed sudden death of entanglement at exceptional points
Subhadeep Chakraborty, Amarendra K. Sarma
Almost a decade ago, physicists encountered a strange quantum phenomenon that predicts an unusual death of entanglement under the influence of local noisy environment,known as enta…
Entanglement dynamics of two coupled mechanical oscillators in modulated optomechanics
Subhadeep Chakraborty, Amarendra K. Sarma
We study the entanglement dynamics of two coupled mechanical oscillators, within a modulated optomechanical system. We find that, depending on the strength of the mechanical coupli…
Qubit assisted enhancement of quantum correlations in an optomechanical system
Subhadeep Chakraborty, Amarendra Kumar Sarma
We perform a theoretical study on quantum correlations in an optomechanical system where the mechanical mirror is perturbatively coupled to an auxiliary qubit. In our study, we con…
