Coherence Estimation Beyond the Liouvillian Gap in a Finite Nonequilibrium System
Sonali Brahma, Trishna Kalita, Himangshu Prabal Goswami
We investigate the estimation of bath-induced coherence in a finite quantum system interacting with thermal reservoirs. Enhancement of coherence estimation is transient and the est…
Thermodynamics of a biophotomimetic nonreciprocal quantum battery
Trishna Kalita, Manash Jyoti Sarmah, Himangshu Prabal Goswami
We propose a theoretical model of a fully functional nonreciprocal quantum battery inspired by the architecture of bacterial light-harvesting complexes. We assign functional roles…
Coherence in the Leak and Storage Kurtosis control Ergotropy in Quantum Batteries
Bitap Raj Thakuria, Trishna Kalita, Manash Jyoti Sarmah +1
We introduce a cavity-coupled finite quantum system which can act as a quantum battery by harnessing noise induced coherences. We apply the methodology of full counting statistics…
Fischer Information of a Nonequilibrium Anharmonic Donor-Acceptor Rectifier
Bitap Raj Thakuria, Trishna Kalita, Javed Akhtar +1
We investigate a nonequilibrium donor-acceptor quantum rectifier system coupled to an anharmonic vibrational mode, treating the vibrational dynamics both as a two-level system and…
Predicting Electromagnetically Induced Transparency based Cold Atomic Engines using Deep Learning
Manash Jyoti Sarmah, Himangshu Prabal Goswami
We develop an artificial neural network model to predict quantum heat engines working within the experimentally realized framework of electromagnetically induced transparency. We s…
Efficiency fluctuations of a heat engine with noise induced quantum coherences
Manash Jyoti Sarmah, Himangshu Prabal Goswami
We analyze the efficiency fluctuations of a coherent quantum heat engine coupled to a unimodal cavity using a standard full-counting statistics procedure. The engine's most likely…
