论文摘要
调整一个非常简单的两分量全息型超流体模型，我们可以在探针极限的两个超氟相之间进行一阶相变。受到潜在景观讨论的启发，提供了具有一阶相变的系统的直观物理图片。我们强调的是，全息图完美地提供了某些强耦合系统的广义热力学描述，即使是局部平衡，这使我们能够在静态或实时动力学下仔细研究系统的域壁结构。我们从数值上构建了1D域壁构型，并根据其广义的大电位来计算域壁的表面张力。我们还数值模拟了2D气泡成核过程的实时动力学（全息沸腾）。当气泡半径足够大时，1D域壁的表面张力很好地匹配了2D气泡成核过程的最终状态。
Tuning a very simple two-component holographic superfluid model, we can have a first order phase transition between two superfluid phases in the probe limit. Inspired by the potential landscape discussion, an intuitive physical picture for systems with first order phase transitions is provided. We stress that holography perfectly offers a generalized thermodynamic description of certain strongly coupled systems even out of local equilibrium, which enables us to carefully study domain wall structures of the system under first order phase transitions, either static or in real time dynamics. We numerically construct the 1D domain wall configuration and compute the surface tension of the domain wall from its generalized grand potential. We also numerically simulate the real time dynamics of a 2D bubble nucleation process (holographic boiling). The surface tension of the 1D domain wall nicely matches the final state of the 2D bubble nucleation process when the bubble radius is large enough.
