Witnessing Nonequilibrium Entanglement Dynamics in a Strongly Correlated Fermionic Chain
driven out of equilibrium. We use a multipartite entanglement witness, the quantum Fisher information, to study the dynamics of a paradigmatic fermion chain undergoing a time-dependent change of the Coulomb [...] D. R.
