Strong Evidence In Favor OF The Existence Of S-Matrix For Strings In Plane Waves
Dongsu Bak, Mohammad M. Sheikh-Jabbari
Field theories on the plane wave background are considered. We discuss that for such field theories one can only form 1+1 dimensional freely propagating wave packets. We analyze tr…
Thoughts on Big Bang
Dongsu Bak
We present a consistent framework that enables us to understand the big bang singularity of our universe.
Supertubes connecting D4 branes
Dongsu Bak, Kimyeong Lee
We find and explore a class of dyonic instanton solutions which can be identified as the supertubes connecting two D4 branes. They correspond to a single monopole string and a pair…
BPS equations in Six and Eight Dimensions
Dongsu Bak, Kimyeong Lee, Jeong-Hyuck Park
We consider the maximal supersymmetric pure Yang-Mills theories on six and eight dimensional space. We determine, in a systematic way, all the possible fractions of supersymmetry p…
Supersymmetric Brane-Antibrane Systems: Matrix Model Description, Stability and Decoupling Limits
Dongsu Bak, Nobuyoshi Ohta, Mohammad M. Sheikh-Jabbari
After reviewing the supertubes and super brane-antibrane systems in the context of matrix model, we look for more general higher-dimensional configurations. For D3-bar{D3}, we find…
Supersymmetric Branes in the Matrix Model of PP Wave Background
Dongsu Bak
We consider the matrix model associated with pp-wave background and construct supersymmetric branes. In addition to the spherical membrane preserving 16 supersymmetries, one may co…
