(d+1)维引力与时空填充带电薄膜耦合的模型被用来研究反反应的影响。由这个简单模型产生的带电黑洞反映了规范场的非线性，并且在热力学上是稳定的。通过对体系涨落的分析，我们证实了在较低的温度(或较大的化学势)下，膜的反反应效应占主导地位。我们还给出了计算直流电导率的Iqbal和Liu策略的推广，其中包含了规范场涨落的质量项。这个质量项给出了交流电导率的虚部中零频极点的残余值，以及直流电导率与体积半径的关系。
A bstractA model consisting of (d+1)-dimensional gravity coupled to spacetime filling charged branes is used to study the effects of backreaction. The charged black holes arising from this simple model reflect the non-linearity of the gauge field and are thermodynamically stable. By analysing fluctuations of the system we corroborate that at low values of the temperature (or large chemical potential) backreaction effects from the branes are dominant. We also provide a generalisation of the Iqbal and Liu strategy to calculate the DC conductivity, in which a mass term for the gauge field fluctuation is included. This mass term gives the value of the residue of the pole at zero frequency in the imaginary part of the AC conductivity, as well as the running of the DC conductivity with the bulk radius.
