Growth of mutual information in a quenched one-dimensional open quantum many body system
Somnath Maity, Souvik Bandyopadhyay, Sourav Bhattacharjee +1
We study the temporal evolution of the mutual information (MI) in a one-dimensional Kitaev chain, coupled to a fermionic Markovian bath, subsequent to a global quench of the chemic…

One-dimensional quantum many body systems with long-range interactions
Somnath Maity, Utso Bhattacharya, Amit Dutta
The presence of algebraically decaying long-range interactions may alter the critical as well as topological behaviour of a quantum many-body systems. However, when the interaction…
