全息导体新词典的唯象构造

Phenomenological Construction of New Dictionaries for Holographic Conductors

Hironori Hoshino, Shin Nakamura

摘要:

我们提出了新的字典全息导体,使我们能够计算系统中的载流子的载流子密度和平均速度。不同于电荷密度的载流子密度是正和负电荷的总数密度。平均速度是所有载流子速度的平均值。这些量与体场边界值所给出的源不共轭,不能用全息中的常规方法计算。本文介绍了一个电荷输运的唯象模型,并通过与全息图的比较建立了电荷输运的字典。我们证明了平均速度与探测D-膜世界体积上的模拟黑洞的速度一致,并且可以从涨落谱中读出。

英文摘要:

We propose new dictionaries for holographic conductors that enable us to compute carrier densities and mean velocities of charge carriers in the system. The carrier density, which differs from the charge density, is the total number density of both the positive and the negative charge carriers. The mean velocity is the mean value of the velocities of all charge carriers. These quantities are not conjugate to the sources that are given by boundary values of bulk fields, and we cannot compute them by using the conventional method in holography. In the present work, we introduce a phenomenological model of charge transport, and we establish the dictionary by comparing the results of the phenomenological model and those from the holography. We show that the mean velocity agrees with the velocity of an analog black hole on the worldvolume of the probe D-brane, and it can be read from the spectrum of the fluctuations.
