论文摘要
在存在化学势和温度的情况下，我们全息研究了具有临界点的非统一量子场理论中的子区域的复杂性。我们提出了一种新的解释，根据该解释，国家需要（更多）指定的信息，表征（UN）稳定的热力学解决方案。我们分别观察到化学潜力和温度对全息次区域复杂性的增加和下降。这两种相反的行为导致混合状态的子区域复杂性与零温度保形场理论相同。我们还介绍了全息次区域复杂性的最小值和最大值（接近临界点附近的值）之间的差异的新描述，作为进行计算工作的资源，以准备远离该州的临界点附近的状态。我们还计算关键指数。
In the presence of chemical potential and temperature, we holographically study subregion complexity in a non-conformal quantum field theory with a critical point. We propose a new interpretation according to which the states, needing (more) less information to be specified, characterize the (un) stable thermodynamical solutions. We observe the increasing and decreasing effects of chemical potential and temperature on holographic subregion complexity, respectively. These two opposite behaviors lead to a point where subregion complexity of the mixed state is the same as this value for a zero temperature conformal field theory. We also present a new description of the difference between the minimum and the maximum value (the value near the critical point) of holographic subregion complexity as a resource for doing computational work to prepare the state near the critical point from the state far from it. We also calculate the critical exponent.
