AdS中的磁膜溶液

Magnetic Brane Solutions in AdS

Eric D'Hoker, Per Kraus

摘要:

在背景磁场存在的情况下,我们在R^{3,1}上构造了与N=4 SYM理论对偶的Einstein-Maxwell理论的渐近AdS_5解.这些解在AdS_5和近视界AdS_3 \times T^2之间插值。近视界区的中心荷,因此溶液的低温熵,被发现是自由N=4 SYM理论的\sqrt{4\over 3}倍。熵在零温度时为零。我们还提出了这些解决方案的推广到任意时空维数。

英文摘要:

We construct asymptotically AdS_5 solutions of Einstein-Maxwell theory dual to N=4 SYM theory on R^{3,1} in the presence of a background magnetic field. The solutions interpolate between AdS_5 and a near horizon AdS_3\times T^2. The central charge of the near horizon region, and hence low temperature entropy of the solution, is found to be \sqrt{4\over 3} times that of free N=4 SYM theory. The entropy vanishes at zero temperature. We also present the generalization of these solutions to arbitrary spacetime dimensionality.
