Yoshinori Matsuo, Sang-Jin Sin, Shingo Takeuchi, Takuya Tsukioka

摘要:

我们研究了在五维Reissner-Nordstrom-AdS背景的流体动力学中的Chern-Simons项的影响。我们解决了运动方程的解耦问题,并明确地计算了滞后格林函数。然后我们发现,陈-西蒙斯项诱导的异常效应所造成的磁导率。它是温度的增函数,从零温度时的非零值到无限温度时的两倍值。

英文摘要:

We study the effects of the Chern-Simons term in the hydrodynamics of the five-dimensional Reissner-Nordstrom-AdS background. We work out the decoupling problem of the equations of motion and calculate the retarded Green functions explicitly. We then find that the Chern-Simons term induces the magnetic conductivity caused by the anomaly effect. It is increasing function of temperature running from a non-zero value at zero temperature to the twice the value at infinite temperature.
