Evolution of entanglement entropy following a quantum quench: Analytic results for the XY chain in a transverse magnetic field
The non-equilibrium evolution of the block entanglement entropy is investigated in the XY chain in a transverse magnetic field after the Hamiltonian parameters are suddenly changed from and to arbitrary values. Using Toeplitz matrix representation and multidimensional phase methods, we provide analy...
