Exchange Fluctuation Theorems for Non-Markovian Baths in Quantum Collisional Model
Sayan Mondal, Sukrut Mondkar, Ujjwal Sen
The quantum exchange fluctuation theorem relates the probabilities of observing heat transfer along and against the temperature gradient between thermal baths at different temperat…
Resource-resolved quantum fluctuation theorems in end-point measurement scheme
Sukrut Mondkar, Sayan Mondal, Ujjwal Sen
Fluctuation theorems provide universal constraints on nonequilibrium energy and entropy fluctuations, making them a natural framework to assess how and to what extent quantum resou…
Mpemba effect in self-contained quantum refrigerators: Accelerated cooling
Sayan Mondal, Ujjwal Sen
We consider the qubit-qutrit model of self-contained quantum refrigerator and observe the quantum Mpemba effect in its cooling. In this system, the qutrit acts as the refrigerator…
Quantum sensing with ultracold simulators in lattice and ensemble systems: a review
Keshav Das Agarwal, Sayan Mondal, Ayan Sahoo +3
Sensing of parameters is an important aspect in all disciplines, with applications ranging from fundamental science to medicine. Quantum sensing and metrology is an emerging field…
