Increasing quantum speed limit via non-uniform magnetic field
Srishty Aggarwal, Banibrata Mukhopadhyay, Subhashish Banerjee +2
Quantum speed limit (QSL) defines the theoretical upper bound on how fast a quantum system can evolve between states. It imposes a fundamental constraint on the rate of quantum inf…
Gravitational Influence on the Quantum Speed Limit in Flavor Oscillations of Neutrino-Antineutrino System
Abhishek Kumar Jha, Banibrata Mukhopadhyay, Mriganka Dutta +2
We investigate the quantum speed limit (QSL) during the time evolution of neutrino-antineutrino system under the influence of the gravitational field of a spinning primordial black…
Influence of gravity on the quantum speed limit in neutrino oscillations
Abhishek Kumar Jha, Mriganka Dutta, Subhashish Banerjee +1
The quantum speed limits (QSLs) determine the minimal amount of time required for a quantum system to evolve from an initial to a final state. We investigate QSLs for the unitary e…
Quantum Thermal Analogs of Electric Circuits: A Universal Approach
Devvrat Tiwari, Samyadeb Bhattacharya, Subhashish Banerjee
In this work, we develop a panoramic schematic of quantum thermal analogs of electric circuits in the steady state regime. We establish the foundations of said premise by defining…
Quantum Thermodynamics of Open Quantum Systems: Nature of Thermal Fluctuations
Neha Pathania, Devvrat Tiwari, Subhashish Banerjee
We investigate the thermodynamic behavior of open quantum systems through the Hamiltonian of Mean Force, focusing on two models: a two-qubit system interacting with a thermal bath…
Quantum speed limit and nonclassicality in open quantum system models using the Wigner function
Arti Gaharwar, Devvrat Tiwari, Subhashish Banerjee
The quantum speed limit and the Wigner function of open system models are studied. To this end, we use the phase covariant and a two-qubit model interacting with a squeezed thermal…
Probing violation and mass ordering in neutrino oscillations in matter through quantum speed limits
Subhadip Bouri, Abhishek Kumar Jha, Subhashish Banerjee
The quantum speed limits (QSLs) set fundamental lower bounds on the time required for a quantum system to evolve from a given initial state to a final state. In this work, we inves…
Bipartite OTOC in open quantum systems: information scrambling and irreversibility
Baibhab Bose, Devvrat Tiwari, Subhashish Banerjee
The field of information scrambling has seen significant growth over the last decade, where the out-of-time-ordered correlator (OTOC) has emerged as a prominent tool to probe it. I…
Strong coupling non-Markovian quantum thermodynamics of a finite-bath system
Devvrat Tiwari, Baibhab Bose, Subhashish Banerjee
The focus is on understanding the quantum thermodynamics of strongly coupled non-Markovian quantum systems. To this end, a non-trivial, non-Markovian model of a central spin surrou…
