On co-dimension two defect operators
Jiang Long
Conformal symmetry is broken by a flat or spherical defect operator . We show that this defect operator, may be identified as a pair of twist operators which are inser…
Higher Spin Entanglement Entropy
Jiang Long
In this paper, we develop a perturbation formulation to calculate the single interval higher spin Rnyi and entanglement entropy for two dimensional conformal field theor…
Strong Subadditivity and Emergent Surface
Bin Chen, Jiang Long
In this paper, we introduce two bounds which we call the Upper Differential Entropy and the Lower Differential Entropy for an infinite family of intervals(strips) in quantum field…
Hidden Conformal Symmetry and Quasi-normal Modes
Bin Chen, Jiang Long
We provide an algebraic way to calculate the quasi-normal modes of a black hole, which possesses a hidden conformal symmetry. We construct an infinite tower of quasi-normal modes f…
Hidden Conformal Symmetry of Extremal Black Holes
Bin Chen, Jiang Long, Jia-ju Zhang
We study the hidden conformal symmetry of the extremal black holes. We introduce a new set of conformal coordinates to write the generators. We find that the Laplacian of…
