Lovelock引力中的量子粘性

The Quantum Viscosity Bound In Lovelock Gravity

Fu-Wen Shu

摘要:

基于有限温度AdS/CFT对应,我们计算了任意阶Lovelock理论中剪切粘滞系数与熵密度的比值。结果表明,除了Gauss-Bonnet项外,其它Lovelock修正项对$η/s$的值没有贡献.这一结果与Escherstein和Medved的预测是一致的。

英文摘要:

Based on the finite-temperature AdS/CFT correspondence, we calculate the ratio of shear viscosity to entropy density in any Lovelock theories to any order. Our result shows that any Lovelock correction terms except the Gauss-Bonnet term have no contribution to the value of $η/s$. This result is consistent with that of Brustein and Medved's prediction.
