Nan Bai, Yi-hong Gao, Xiao-Bao Xu · arXiv (Cornell University) · 2013
In this note we compute mutual information between two intervals in CFTs dual to extremal BTZ (UV CFT) and near horizon limit of extremal BTZ (IR CFT) using the replica technique in some limiting regimes, which can be compared with holographic description.
