论文摘要
我们研究了带有标量头发的渐近广告黑洞系统的混合状态纠缠。通过数值计算，我们发现全息纠缠熵（HEE）具有系统参数的非单调行为，具体取决于子区域的大小。另外，在系统参数的某些范围内，共同信息（MI）还显示了非单调行为。但是，纠缠楔形最小横截面（EWC）是一种混合状态纠缠措施，随着ADS半径而单调地增加。同时，显示非单调的温度。我们还对上述现象进行了分析理解。
We study the mixed state entanglement of an asymptotic AdS black hole system with scalar hair. Through numerical calculations, we find that the holographic entanglement entropy (HEE) presents a non-monotonic behavior with the system parameter, depending on the size of the subregion. In addition, the mutual information (MI) also shows non-monotonic behavior in certain ranges of system parameters. However, the entanglement wedge minimum cross-section (EWCS), which is a mixed state entanglement measure, increases monotonically with the AdS radius; meanwhile, shows non-monotonic with the temperature. We also give analytical understandings of the phenomena above.
