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…
