Trends of information backflow in disordered spin chains
Sudipto Singha Roy, Utkarsh Mishra, Debraj Rakshit
We investigate the trends of information backflow associated with the dynamics of a sub-part of a disordered spin-1/2 transverse field Heisenberg chain for different regimes of the…
Disordered Kitaev chain with long-range pairing: Loschmidt echo revivals and dynamical phase transitions
Utkarsh Mishra, R. Jafari, Alireza Akbari
We explore the dynamics of long-range Kitaev chain by varying pairing interaction exponent, . It is well known that distinctive characteristics on the nonequilibrium dynamics of…
Dynamical quantum correlations after sudden quenches
Utkarsh Mishra, Hadi Cheraghi, Saeed Mahdavifar +2
We employ the mean-field approach in the fermionic picture of the spin-1/2 XXZ chain to investigate the dynamics of bipartite quantum discord and concurrence under sudden quenching…
