手征热效应
The Chiral Heat Effect
摘要:
本文研究了在弯曲空间中由手征磁效应激发的具有手征反常的(3+1)维理论的热响应。我们发现了一种新的现象,称为手征热效应,即使在平坦的空间中,也会产生横向于温度梯度的热流。这种效应有望在QCD实验中观察到,同时也有望在手征磁效应中观察到。我们研究了具有挠率的时空的一种类似拓扑效应。本文还讨论了D3/D 7模型和Sakai-Sugimoto模型的全息构造。
英文摘要:
We consider the thermal response of a (3+1)-dimensional theory with a chiral anomaly on a curved space motivated by the chiral magnetic effect. We find a new phenomenon, called the chiral heat effect, such that the thermal current is induced transverse to a gradient of the temperature even on a flat space. This effect is expected to be observed in QCD experiment as well as the chiral magnetic effect. We study a similar topological effect on the spacetime with a torsion. A holographic construction is also discussed with the D3/D7 and the Sakai-Sugimoto models.
