Decoherence-free subspaces and Markovian revival of genuine multipartite entanglement in a dissipative system
Shubhodeep Gangopadhyay, Vinayak Jagadish, R. Srikanth
We investigate the dynamics of genuine multipartite entanglement (GME) in a system of qubits () collectively interacting with a common zero temperature bosonic bath char…

Dissipation in fermionic two-body continuous-time quantum walk under the steepest entropy ascent formalism
Rohit Kishan Ray, R. Srikanth, Sonjoy Majumder
Quantum walks play a crucial role in quantum algorithms and computational problems. Many-body quantum walks can reveal and exploit quantum correlations that are unavailable for sin…

Eternal non-Markovianity of qubit maps
Vinayak Jagadish, R. Srikanth
As is well known, unital Pauli maps can be eternally non-CP-divisible. In contrast, here we show that in the case of non-unital maps, eternal non-Markovianity in the non-unital par…
