Strongly coupled quantum Otto cycle with single qubit bath
Sagnik Chakraborty, Arpan Das, Dariusz Chruściński
We discuss a model of a closed quantum evolution of two-qubits where the joint Hamiltonian is so chosen that one of the qubits acts as a bath and thermalize the other qubit which i…
Precision bound and optimal control in periodically modulated continuous quantum thermal machines
Arpan Das, Shishira Mahunta, Bijay Kumar Agarwalla +1
We use Floquet formalism to study fluctuations in periodically modulated continuous quantum thermal machines. We present a generic theory for such machines, followed by specific ex…
Quantum homogenization in non-Markovian collisional model
Tanmay Saha, Arpan Das, Sibasish Ghosh
Collisional models are a category of microscopic framework designed to study open quantum systems. The framework involves a system sequentially interacting with a bath comprised of…
