Vortex Strings and Nonabelian sine-Gordon Theories
Q-Han Park, H. J. Shin
We generalize the Lund-Regge model for vortex string dynamics in 4-dimensional Minkowski space to the arbitrary n-dimensional case. The n-dimensional vortex equation is identified…
Vortex String Dynamics in an External Antisymmetric Tensor Field
K. Lee, Q-Han Park, H. J. Shin
We study the Lund-Regge equation that governs the motion of strings in a constant background antisymmetric tensor field by using the duality between the Lund-Regge equation and the…
Two Dimensional Anti-de Sitter Space and Discrete Light Cone Quantization
Jin-Ho Cho, Taejin Lee, Gordon Semenoff
We realize the two dimensional anti-de Sitter () space as a Kaluza-Klein reduction of the space in the framework of the discrete light cone quantization (DLCQ). Intr…
AdS_3 Black Hole Entropy and the Spectral Flow on the Horizon
Jin-Ho Cho, Soonkeon Nam
We consider the entropy problem of AdS_3 black holes using the conformal field theory at the horizon. We observe that the supersymmetry is enhanced at the horizon of massless AdS_3…
