Exactly Soluble Dynamics of (p,q) String Near Macroscopic Fundamental Strings
Dongsu Bak, Soo-Jong Rey, Ho-Ung Yee
We study dynamics of Type IIB bound-state of a Dirichlet string and n fundamental strings in the background of N fundamental strings. Because of supergravity potential, the bound-s…
A Geometric Look on the Microstates of Supertubes
Dongsu Bak, Yoshifumi Hyakutake, Seok Kim +1
We give a geometric interpretation of the entropy of the supertubes with fixed conserved charges and angular momenta in two different approaches using the DBI action and the superm…
Phase Moduli Space of Supertubes
Dongsu Bak, Yoshifumi Hyakutake, Nobuyoshi Ohta
We study possible deformations of BPS supertubes keeping their conserved charges fixed. We show that there is no flat direction to closed supertubes of circular cross section with…
Dilatonic Repulsons and Confinement via the AdS/CFT Correspondence
Dongsu Bak, Michael Gutperle, Shinji Hirano +1
We study a class of dilatonic deformations of asymptotically AdS_5 X S^5 geometry analytically and numerically. The spacetime is non-supersymmetric and suffers from a naked singula…
