Multi-BPS D-vortices
Inyong Cho, Taekyung Kim, Yoonbai Kim
We investigate the BPS configuration of the multi D-vortices produced from the D22 system. Based on the DBI-type action with a Gaussian-type runaway potential for a…
Tachyon Vacuum Solution in Open String Field Theory with Constant B Field
Akira Ishida, Chanju Kim, Yoonbai Kim +2
We show that Schnabl's tachyon vacuum solution is an exact solution of the equation of motion of Witten's open bosonic string field theory in the background of constant antisymmetr…
Negative-Tension Branes and Tensionless 1/2 Brane in Boundary Conformal Field Theory
Akira Ishida, Chanju Kim, Yoonbai Kim +1
In the framework of boundary conformal field theory we consider a flat unstable D-brane in the presence of a large constant electromagnetic field. Specifically, we study the cas…
Lower Dimensional Branes in Boundary Conformal Field Theory
Akira Ishida, Yoonbai Kim, Chanju Kim +1
In the presence of constant background electromagnetic fields, we discuss three types of exactly marginal boundary tachyon operators for static kinks in boundary conformal field th…
