Abstract

We study the time evolution of holographic mutual and tripartite information for a zero temperature CFTCFT, derives to a non-relativistic thermal Lifshitz field theory by a quantum quench. We observe that the symmetry breaking does not play any role in the phase space, phase of parameters of sub-systems, and the length of disentangling transition. Nevertheless, mutual and tripartite information indeed depend on the rate of symmetry breaking. We also find that for large enough values of δt\delta t the quantity teqδt1t_{eq}\delta t^{-1}, where δt\delta t and teqt_{eq} are injection time and equilibration time respectively, behaves universally, i.e.i.e. its value is independent of length of separation between sub-systems. We also show that tripartite information is always non-positive during the process indicates that mutual information is monogamous.
