Tachyon Tube and Supertube
Chanju Kim, Yoonbai Kim, O-Kab Kwon +1
We search for tubular solutions in unstable D3-brane. With critical electric field E=1, solutions representing supertubes, which are supersymmetric bound states of fundamental stri…
Brane World of Warp Geometry: An Introductory Review
Yoonbai Kim, Chong Oh Lee, Ilbong Lee +1
Basic idea of Randall-Sundrum brane world model I and II is reviewed with detailed calculation. After introducing the brane world metric with exponential warp factor, metrics of Ra…
Tachyon Kinks on Unstable Dp-branes
Chanju Kim, Yoonbai Kim, O-Kab Kwon +1
In the context of tachyon effective theory coupled to Born-Infeld electromagnetic fields, we obtain all possible singularity-free static flat configurations of codimension one on u…
Tachyon Kinks
Chanju Kim, Yoonbai Kim, Chong Oh Lee
We study Born-Infeld type tachyonic effective action of unstable D2-brane with a runaway potential and find rich structure of static regular solitonic solutions. There exists only…
Classical stability of stringy wormholes in flat and AdS spaces
Jin Young Kim, Yoonbai Kim, James E. Hetrick
We study small fluctuations of the stringy wormhole solutions of graviton-dilaton-axion system in arbitrary dimensions. We show under O()-symmetric harmonic perturbation that th…
Cosmology of Rolling Tachyon
Chanju Kim, Hang Bae Kim, Yoonbai Kim +1
We study dynamics of rolling tachyon and Abelian gauge field on unstable D-branes, of which effective action is given by Born-Infeld type nonlocal action. Possible cosmological evo…
