Abstract：We will introduce our recent progress in the relationship between the holographic phase transition and mixed state entanglement. In the two thermal phase transitions of superconducting phase transition and Hawking-Page phase transition, the quantum entanglement of mixed states will show scaling laws. The scaling law of phase transition comes from the perturbation relationship between the background geometry and the reduced parameters at the critical point. The critical exponents of mixed state entanglement are different in superconducting phase transition and Hawking page phase transition, which essentially comes from their different mechanisms of phase transition. In addition, we will also discuss the possible interesting phenomena in quantum phase transitions.
