Quantum speed limit constraints on a nanoscale autonomous refrigerator
Chiranjib Mukhopadhyay, Avijit Misra, Samyadeb Bhattacharya +1
Quantum speed limit, furnishing a lower bound on the required time for the evolution of a quantum system through the state space, imposes an ultimate natural limitation to the dyna…
Universal quantum uncertainty relations between non-ergodicity and loss of information
Natasha Awasthi, Samyadeb Bhattacharya, Aditi Sen De +1
We establish uncertainty relations between information loss in general open quantum systems and the amount of non-ergodicity of the corresponding dynamics. The relations hold for a…
Wave-particle duality employing quantum coherence in superposition with non-orthogonal pointers
Sreetama Das, Chiranjib Mukhopadhyay, Sudipto Singha Roy +3
We propose the notion of quantum coherence for superpositions over states which are not necessarily mutually orthogonal. This anticipatedly leads to a resource theory of non-orthog…
Dynamics and thermodynamics of a central spin immersed in a spin bath
Chiranjib Mukhopadhyay, Samyadeb Bhattacharya, Avijit Misra +1
An exact reduced dynamical map along with its operator sum representation is derived for a central spin interacting with a thermal spin environment. The dynamics of the central spi…
