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…
Energy Cost of Creating Quantum Coherence
Avijit Misra, Uttam Singh, Samyadeb Bhattacharya +1
We consider the physical situations where the resource theories of coherence and thermodynamics play competing roles. In particular, we study the creation of quantum coherence usin…
Evolution of coherence and non-classicality under global environmental interaction
Samyadeb Bhattacharya, Subhashish Banerjee, Arun Kumar Pati
A master equation has been constructed for a global system-bath interaction both in the absence as well as presence of non-Markovian noise. For the memoryless case, it has been exa…
