Abstract
We investigate the dynamical evolution of entanglement entropy in a holographic superconductor model by quenching the source term of the dual charged scalar operator By access to the full background geometry the holographic entanglement entropy is calculated for a strip geometry at the AdS boundary It is found that the entanglement entropy exhibits a robust nonmonotonic behaviour in time independent of the strength of Gaussian quench and the size of the strip it first displays a small dip then grows linearly and finally saturates In particular the linear growth velocity of the entanglement entropy has an upper bound for strip with large width the equilibrium value of the nonlocal probe at late time shows a power law scaling behaviour with respect to the quench strength moreover the entanglement entropy can uncover the dynamical transition at certain critical quench strength which happens to coincide with the one obtained form the dynamical evolution of scalar order parameterThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
