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…
String Fluid, Tachyon Matter, and Domain Walls
O-Kab Kwon, Piljin Yi
We study classical dynamics of an open string tachyon of unstable D-brane coupled to the gauge field . In the vacuum with vanishing potential, V=0, two fluid-like degre…
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…
Type IIA Supergravity Excitations in Plane-Wave Background
O-Kab Kwon, Hyeonjoon Shin
We study the low-lying excitations of Type IIA superstring theory in a plane wave background with 24 supersymmetries. In the light-cone gauge, the superstring action has ${\cal N}=…
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…
Electromagnetic String Fluid in Rolling Tachyon
Chanju Kim, Hang Bae Kim, Yoonbai Kim +1
We study Born-Infeld type effective action for unstable D3-brane system including a tachyon and an Abelian gauge field, and find the rolling tachyon with constant electric and magn…
