Distribution of the entanglement entropy of a non-ergodic quantum state
Devanshu Shekhar, Pragya Shukla
We theoretically derive the probability densities of the entanglement measures of a pure non-ergodic many-body state, represented in a bipartite product basis and with its reduced…

Edge of entanglement in non-ergodic states: a complexity parameter formulation
Devanshu Shekhar, Pragya Shukla
We analyze the subsystem size scaling of the entanglement entropy of a non-ergodic pure state that can be described by a multi-parametric Gaussian ensemble of complex matrices in a…
