冷全息物质的普适性质

Universal properties of cold holographic matter

Niko Jokela, Alfonso V. Ramallo

摘要:

我们研究了生活在两组D膜交叉处的低能理论中形成的全息量子液体的集体激发。相应的场论对偶是一个超对称的杨-米尔斯理论,在规范群的基本表象中具有无质量的超多重态,一般存在于无味理论的缺陷上。工作在淬火(探针)近似,我们专注于确定这些系统的普遍性质。我们分析了它们的热力学,第一声速,扩散常数和零声速。我们研究了温度,化学势,和磁场对这些量的影响,以及相应的碰撞/流体动力学交叉。我们还推广了所有共形$AdS_4$情况下的替代量子化,并研究了任意子的量子化。

英文摘要:

We study the collective excitations of holographic quantum liquids formed in the low energy theory living at the intersection of two sets of D-branes. The corresponding field theory dual is a supersymmetric Yang-Mills theory with massless matter hypermultiplets in the fundamental representation of the gauge group which generically live on a defect of the unflavored theory. Working in the quenched (probe) approximation, we focus on determining the universal properties of these systems. We analyze their thermodynamics, the speed of first sound, the diffusion constant, and the speed of zero sound. We study the influence of temperature, chemical potential, and magnetic field on these quantities, as well as on the corresponding collisionless/hydrodynamic crossover. We also generalize the alternative quantization for all conformally $AdS_4$ cases and study the anyonic correlators.
