Entanglement measures and non-equilibrium dynamics of quantum many-body systems: a path integral approach
Roopayan Ghosh, Nicolas Dupuis, Arnab Sen +1
We present a path integral formalism for expressing matrix elements of the density matrix of a quantum many-body system between any two coherent states in terms of standard Matsuba…

Disorder-induced Enhancement of Entanglement Growth in One Dimension: Information Leakage at the scale of localization length
Roopayan Ghosh, Arnab Das
When a group of compactly packed free fermions is allowed to spread over an empty one-dimensional lattice, the spreading particles can create entanglement between different parts o…
