Control of Multipartite Entanglement through Anisotropy against Thermal Noise
Samudra Sur, Saikat Sur
Preserving multipartite entanglement in open many-body quantum systems is fundamentally limited by unavoidable environmental noise. We study the open-system dynamics of multipartit…

Interplay of Noise and Reservoir-induced Decoherence in Persistent Currents
Samudra Sur, Thierry Giamarchi
Persistent current is a hallmark of quantum phase coherence. We study the fate of the persistent current in a non-equilibrium setting, where a tight-binding ring is subjected to st…
