论文摘要

我们考虑了与引力异常强烈相互作用的血浆的全息模型。在此模型中,我们计算系统在有限温度和化学潜力下对外部电磁和重力场的奇偶校验响应。在线性化的流体/重力双重性中工作,我们在梯度扩展中执行了最高的计算。除了重现手性磁(CME)和涡旋(CVE)效应外,由于重力异常,我们还获得了对CME和CVE的梯度校正。此外,我们发现能量摩肌和电流对重力场的反应类似于引力异常。能量摩托明响应是与全息理论中量子异常有关的第一个纯重力转运效应。

We consider a holographic model of strongly interacting plasma with a gravitational anomaly. In this model, we compute parity-odd responses of the system at finite temperature and chemical potential to external electromagnetic and gravitational fields. Working within the linearized fluid/gravity duality, we performed the calculation up to the third order in gradient expansion. Besides reproducing the chiral magnetic(CME) and vortical (CVE) effects we also obtain gradient corrections to the CME and CVE due to the gravitational anomaly. Additionally, we find energy-momentum and current responses to the gravitational field similarly determined by the gravitational anomaly. The energy-momentum response is the first purely gravitational transport effect that has been related to quantum anomalies in holographic theories.
