高阶导数修正下的非相对论性D3-brane

Non-relativistic D3-brane in the presence of higher derivative corrections

Mohsen Alishahiha, Ahmad Ghodsi

摘要:

利用IIB型超引力作用量的α ^3项,我们研究了非相对论非极值D3-膜的高阶修正。利用校正的解决方案,我们评估修正温度,熵和剪切粘度。我们还计算的eta/s比,虽然在超引力近似的有效性范围内,并在最低阶的校正的普遍约束的尊重,有一个违反的约束时,考虑到更高的扩展项的可能性。

英文摘要:

Using alpha'^3 terms of type IIB supergravity action we study higher order corrections to the non-relativistic non-extremal D3-brane. Utilizing the corrected solution we evaluate corrections to temperature, entropy and shear viscosity. We also compute the eta/s ratio which although within the range of validity of the supergravity approximation and in the lowest order of the correction the universal bound is respected, there is a possibility for a violation of the bound when higher terms in the expansion are taken into account.
