Entanglement dynamics after a quench in Ising field theory: a branch point twist field approach
Abstract We extend the branch point twist field approach for the calculation of entanglement entropies to time-dependent problems in 1+1-dimensional massive quantum field theories. We focus on the simplest example: a mass quench in the Ising field theory from initial mass m 0 to final mass m. The ma...
