Scalar Hair of Global Defect and Black Brane World
Yoonbai Kim, Dong Hyun Park
We consider a complex scalar field in (p+3)-dimensional bulk with a negative cosmological constant and study global vortices in two extra-dimensions. We reexamine carefully the cou…
Factorization and generalized *-products
Youngjai Kiem, Dong Hyun Park, Sangmin Lee
The generalized *-products, or the -products, appear both in the one-loop effective action of noncommutative Yang-Mills theories and in the coupling of a closed string to N op…
Open string derivation of winding states in thermal noncommutative field theories
Youngjai Kiem, Dong Hyun Park, Haru-Tada Sato
The `winding state' behavior appears in the two-loop nonplanar contribution to the partition function in thermal noncommutative field theories. We derive this feature directly from…
Stretched strings and worldsheets with a handle
Youngjai Kiem, Dong Hyun Park, Haru-Tada Sato
In the presence of the constant background NS two-form gauge field, we construct the worldsheet partition functions, bulk propagators and boundary propagators for the worldsheets w…
Geodesic Motions in 2+1 Dimensional Charged Black Holes
Dong Hyun Park, Seung-ho Yang
We study the geodesic motions of a test particle around 2+1 dimensional charged black holes. We obtain a class of exact geodesic motions for the massless test particle when the rat…
