论文摘要
我们研究了在有限温度和化学潜力下在探针极限下的全息超流体的几乎关键行为。这使我们能够使用系统的电荷密度来检查完整复合阶参数的耦合动力学。我们通过使用整体中的分析技术来得出一个有效的理论，该理论是对无间隙和伪束模式的长波长极限的有效理论。我们在Hohenberg和Halperin的分类中与模型F匹配构造，并根据热力学和黑洞地平线数据计算复杂的耗散动力学传输系数。我们对相应的模式进行分析，并认为在有限密度下，分散关系在正常相和破碎相之间是不连续的。我们将结果与早期的数值工作进行比较和对比。
We study the nearly critical behaviour of holographic superfluids at finite temperature and chemical potential in their probe limit. This allows us to examine the coupled dynamics of the full complex order parameter with the charge density of the system. We derive an effective theory for the long wavelength limit of the gapless and pseudo-gapped modes by using analytic techniques in the bulk. We match our construction with Model F in the classification of Hohenberg and Halperin and compute the complex dissipative kinetic transport coefficient in terms of thermodynamics and black hole horizon data. We carry out an analysis of the corresponding modes and argue that at finite density the dispersion relations are discontinuous between the normal and the broken phase. We compare and contrast our results with earlier numerical work.
