论文摘要
通过分别使用RT公式和子区域CV构想，我们对两种具有反应的全息D-Wave超导模型进行了数值研究。我们发现HEE和HSC都可以用作这两个D波超导相变的良好探针。由于临界温度TC的自由度缩合，超导阶段的HEE始终低于正常相。但是，对于HSC，它的行为不同，有趣的是，这取决于条带宽度LX和反射\ k {appa}。
By using the RT formula and the subregion CV conjecture respectively, we numerically investigate the holographic entanglement entropy (HEE) and holographic subregion complexity (HSC) for two holographic d-wave superconducting models with backreactions. We find that both the HEE and HSC can be used as good probes to these two d-wave superconducting phase transitions. The HEE of superconducting phase is always lower than that of the normal phase due to the condensation of degrees of freedom below the critical temperature Tc. However, for the HSC, it behaves differently and interestingly, which depends on both the strip-width Lx and backreaction \k{appa}.
