The RN/CFT Correspondence Revisited

Abstract

We reconsidered the quantum gravity description of the near horizon extremal Reissner-Nordstrøm black hole in the viewpoint of the AdS${}_2$/CFT${}_1$ correspondence. We found that, for pure electric case, the right moving central charge of dual 1D CFT is $6Q^2$ which is different from the previous result $6Q^3$ of left moving sector obtained by warped AdS${}_3$/CFT${}_2$ description. We discussed the discrepancy in these two approaches and examined novel properties of our result.
