Reflecting Magnon Bound States
Changrim Ahn, Dongsu Bak, Soo-Jong Rey
In N=4 super Yang-Mills spin chain, we compute reflection amplitudes of magnon bound-state off giant graviton. We first compute the reflection amplitude off Y=0 brane boundary and…
Time dependent black holes and thermal equilibration
Dongsu Bak, Michael Gutperle, Andreas Karch
We study aspects of a recently proposed exact time dependent black hole solution of IIB string theory using the AdS/CFT correspondence. The dual field theory is a thermal system in…
Debye screening in strongly coupled N=4 supersymmetric Yang-Mills plasma
Dongsu Bak, Andreas Karch, Laurence G. Yaffe
Using the AdS/CFT correspondence, we examine the behavior of correlators of Polyakov loops and other operators in N=4 supersymmetric Yang-Mills theory at non-zero temperature. The…
Three dimensional Janus and time-dependent black holes
Dongsu Bak, Michael Gutperle, Shinji Hirano
We show that the three dimensional Janus geometry can be embedded into the type IIB supergravity and discuss its dual CFT description. We also find exact solutions of time dependen…
