调制剪切熵比

A modulated shear to entropy ratio

O. Ovdat, A. Yarom

摘要:

研究了爱因斯坦-麦克斯韦二阶导数引力场平衡空间调制相位下的关联函数。我们发现应力-应力两点函数的适当低频极限与熵密度的比值是可调的。电导率,应力-电流和电流-应力关联函数也被调制。在接近相变的温度下,我们得到了一些关联函数的解析表达式。

英文摘要:

We study correlation functions in an equilibrated spatially modulated phase of Einstein-Maxwell two-derivative gravity. We find that the ratio of the appropriate low frequency limit of the stress-stress two point function to the entropy density is modulated. The conductivity, the stress-current and current-stress correlation functions are also modulated. At temperatures close to the phase transition we obtain analytic expressions for some of the correlation functions.
