Holographic entanglement entropy and complexity for D-wave superconductors

By using the RT formula and subregion CV conjecture respectively, we numerically investigate holographic entanglement entropy (HEE) complexity (HSC) for two d-wave superconducting models with backreactions. We find that both HEE HSC can be used as good probes to these phase transitions. The of is always lower than normal due condensation degrees freedom below critical temperature Tc. However, HSC, it behaves differently interestingly, which depends on strip-width Lx backreaction \k{appa}.
