We study the holographic entanglement entropy in a (d + 1)-dimensional boundary quantum field theory at both the zero and finite temperature. The phase diagrams for the holographic entanglement entropy at various temperatures are obtained by solving the entangled surfaces in the different homology. We also verify the Araki-Lieb inequality and illustrate the entanglement plateau.

We study a non-minimal holographic superconductors model in both non-backreaction and full-backreaction cases using an analytic matching method. We calculate the condensate of the dilaton and the critical temperature of the phase transition. We also study the properties of the electric conductivity in various parameters. (C) 2020 The Authors.
