Entanglement dynamics of many-body quantum states: sensitivity to system conditions and a hidden universality
Devanshu Shekhar, Pragya Shukla
We consider physical Hamiltonians that can be represented by the multiparametric Gaussian ensembles, theoretically derive the state ensembles for its eigenstates and analyze the ef…
Single-particle entanglement dynamics in complex systems
Devanshu Shekhar, Pragya Shukla
We analyze the effect of varying system conditions on the single-particle entanglement entropy for an arbitrary eigenstate of a complex system that can be described by a multiparam…
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…
