DF-strings from D33 as Cosmic Strings
Inyong Cho, Yoonbai Kim, Bumseok Kyae
We study Dirac-Born-Infeld type effective field theory of a complex tachyon and U(1)U(1) gauge fields describing a D33 system. Classical solutions of straig…
BPS D-branes from an Unstable D-brane
Chanju Kim, Yoonbai Kim, Hwang-hyun Kwon +2
We search for exact tachyon kink solutions of DBI type effective action describing an unstable D-brane with worldvolume gauge field turned in both the flat and a curved background.…
Global and Local D-vortices
Yoonbai Kim, Bumseok Kyae, Jungjai Lee
Codimension-two objects on a system of brane-antibrane are studied in the context of Born-Infeld type effective field theory with a complex tachyon and U(1)U(1) gauge field…
BPS D-branes from an Unstable D-brane in a Curved Background
Chanju Kim, Yoonbai Kim, Hwang-hyun Kwon +1
We find exact tachyon kink solutions of DBI type effective action describing an unstable D5-brane with worldvolume gauge field turned on in a curved background. The background of i…
Cosmology of Antisymmetric Tensor Field in D-brane Universe
Eung Jin Chun, Hang Bae Kim, Yoonbai Kim
We analyze homogeneous, anisotropic cosmology driven by a self-interacting ``massive'' antisymmetric tensor field which is present in string theories with D-branes. Time-d…
Exact Rolling Tachyon in Noncommutative Field Theory
Yoonbai Kim, O-Kab Kwon
We study the exact rolling tachyon solutions in DBI type noncommutative field theory with a constant open string metric and noncommutative parameter on an unstable D-brane. Func…
