二维手性反常与AdS/CMT

Chiral anomalies and AdS/CMT in two dimensions

Kristan Jensen

摘要:

我澄清了最近关于二维有限密度系统的全息描述的一些混乱。值得注意的是,在二维共形场论(CFT)中对称流的手征反常完全决定了它们的对称子。重要的例外是具有规范理论的CFT,我们可以将外部电流耦合到该规范理论上,如在探测D3/D3系统中,或在带电BTZ黑洞的假定对偶中。这些系统进行了分析,潜在的凝聚态应用的眼睛。

英文摘要:

I clarify some recent confusion regarding the holographic description of finite-density systems in two dimensions. Notably, the chiral anomaly for symmetry currents in 2d conformal field theories (CFT) completely determines their correlators. The important exception is a CFT with a gauge theory to which we may couple an external current, as in the probe D3/D3 system or the putative dual to the charged BTZ black hole. These systems are analyzed with an eye for potential condensed matter applications.
