Multiscale quantum-defect theory for two interacting atoms in a symmetric harmonic trap
Yujun Chen, Bo Gao
We present a multiscale quantum-defect theory (QDT) for two identical atoms in a symmetric harmonic trap that combines the quantum-defect theory for the van der Waals interaction […
Symmetries of WDVV equations
Yujun Chen, Maxim Kontsevich, Albert Schwarz
We say that a function F(tau) obeys WDVV equations, if for a given invertible symmetric matrix eta^{alpha beta} and all tau \in T \subset R^n, the expressions c^{alpha}_{beta gamma…
Quantum Liouville theory and BTZ black hole entropy
Yujun Chen
In this paper I give an explicit conformal field theory description of (2+1)-dimensional BTZ black hole entropy. In the boundary Liouville field theory I investigate the reducible…
Quasinormal Modes and Black Hole Quantum Mechanics in 2+1 Dimensions
Danny Birmingham, Steven Carlip, Yujun Chen
We explore the relationship between classical quasinormal mode frequencies and black hole quantum mechanics in 2+1 dimensions. Following a suggestion of Hod, we identify the real p…
