Many-body quantum thermal machines in a Lieb-kagome Hubbard model
Saikat Sur, Pritam Chattopadhyay, Madhuparna Karmakar +1
Quantum many-body systems serve as a suitable working medium for realizing quantum thermal machines (QTMs) by offering distinct advantages such as cooperative many-body effects, an…
Quantum Superposition of Two Temperatures
Arun Kumar Pati, Avijit Misra
In the classical world, temperature is a measure of how hot or cold a physical object is. We never find a physical system which can be both hot and cold at the same time. Here, we…
Exact master equation for a spin interacting with a spin bath: Non-Markovianity and negative entropy production rate
Samyadeb Bhattacharya, Avijit Misra, Chiranjib Mukhopadhyay +1
An exact canonical master equation of the Lindblad form is derived for a central spin interacting uniformly with a sea of completely unpolarized spins. The Kraus operators for the…
