Propagation of Light in Doubly Special Relativity
Sung Ku Kim, Sun Myong Kim, Chaiho Rim +1
In an attempt to clarify what is the velocity of a particle in doubly special relativity, we solve Maxwell's equations invariant under the position-space nonlinear Lorentz transfor…
Noncommutative Chern-Simons Solitons
Dongsu Bak, Sung Ku Kim, Kwang-Sup Soh +1
The Chern-Simons theories on a noncommutative plane, which is shown to be describing the quantum Hall liquid, is considered. We introduce matter fields fundamentally coupled to the…
Noncommutative Field Theories and Smooth Commutative Limits
Dongsu Bak, Sung Ku Kim, Kwang-Sup Soh +1
We consider two model field theories on a noncommutative plane that have smooth commutative limits. One is the single-component fermion theory with quartic interaction that vanishe…
Exact Wavefunctions in a Noncommutative Field Theory
Dongsu Bak, Sung Ku Kim, Kwang-Sup Soh +1
We consider the nonrelativistic field theory with a quartic interaction on a noncommutative plane. We compute the four point scattering amplitude within perturbative analysis to al…
Black Hole Decay and Quantum Instantons
Donsu Bak, Sang Pyo Kim, Sung Ku Kim +2
We study the analytic structure of the S-matrix which is obtained from the reduced Wheeler-DeWitt wave function describing spherically symmetric gravitational collapse of massless…
Gravitational Collapse and Calogero Model
Dongsu Bak, Sang Pyo Kim, Sung Ku Kim +2
We study the analytic structure of the S-matrix which is obtained from the reduced Wheeler-DeWitt wave function describing spherically symmetric gravitational collapse of massless…
