Quantum synchronization between two spin chains using pseudo-bosonic equivalence
Jatin Ghildiyal, Manju, Shubhrangshu Dasgupta +1
Quantum synchronization among many spins is an intriguing domain of research. In this paper, we explore the quantum synchronization of two finite chains of spin-1/2 particles, via…
Quantum synchronization and entanglement of indirectly coupled mechanical oscillators in cavity optomechanics: a numerical study
Devender Garg, Manju, Shubhrangshu Dasgupta +1
It is often conjectured that quantum synchronisation and entanglement are two independent properties which two coupled quantum systems may not exhibit at the same time. However, as…
Entanglement as a sufficient condition for quantum synchronization between two mechanical oscillators
Manju, Shubhrangshu Dasgupta, Asoka Biswas
We present an optomechanical model to show that entanglement can be a sufficient condition for quantum synchronization of two mechanical oscillators. As both these entities can be…
Measurement-based quantum Otto engine with a two-spin system coupled by anisotropic interaction: enhanced efficiency at finite times
Chayan Purkait, Asoka Biswas
We have studied the performance of a measurement-based quantum Otto engine (QOE) in a working system of two spins coupled by Heisenberg anisotropic interaction. A non-selective qua…
Motion-induced enhancement of Rabi coupling between atomic ensembles in cavity optomechanics
Anil K. Chauhan, Asoka Biswas
We propose a scheme of enhancement of Rabi coupling between two identical atomic ensembles trapped inside an optical cavity in a membrane-in-the-middle set up. The cavity modes dis…
