Squeezing-Fueled Quantum Otto Engine via Measurement-Induced Cooling: The Two-Qubit Quantum Rabi Model
S R Rathnakaran, Asoka Biswas
We investigate a quantum Otto engine (QOE) constructed from the two-qubit quantum Rabi model, operating within a cavity quantum electrodynamics (QED) architecture. The engine opera…
Multipartite synchronization residuals in driven-dissipative spin networks
Jatin Ghildiyal, Shubhrangshu Dasgupta, Asoka Biswas
We introduce a phase-space measure of quantum synchronization that quantifies relative phase localization for two-qubit and three-qubit systems. This measure is built from the firs…
Quantum synchronization between two strongly driven YIG spheres mediated via a microwave cavity
Jatin Ghildiyal, Shubhrangshu Dasgupta, Asoka Biswas
We present a theoretical study of synchronization between two strongly driven magnon modes indirectly coupled via a single-mode microwave cavity. Each magnon mode, hosted in separa…
Ancilla measurement-based Quantum Otto engine using double-pair spin architecture
S R Rathnakaran, Asoka Biswas
We present a quantum heat engine model utilizing a dual spin-pair architecture, wherein an Otto-like cycle is implemented using a single heat bath. The conventional cold bath is re…
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…
Quasi-probability distribution of work in a measurement-based quantum Otto engine
Chayan Purkait, Shubhrangshu Dasgupta, Asoka Biswas
We study the work statistics of a measurement-based quantum Otto engine, where quantum non-selective measurements are used to fuel the engine, in a coupled spin working system (WS)…
