Domain Walls in Noncommutative Field Theories
Yoonbai Kim, O-Kab Kwon, Chong Oh Lee
We study kinks in a wide class of noncommutative (NC) field theories. We find rich structure of the static kinks in DBI type NC tachyon action for an unstable D-brane with gener…
Noncommutative Tachyon Kinks as D-branes from Unstable D-brane
Rabin Banerjee, Yoonbai Kim, O-Kab Kwon
We study noncommutative (NC) field theory of a real NC tachyon and NC U(1) gauge field, describing the dynamics of an unstable D-brane. For every given set of diagonal component…
Tubular D-branes in Salam-Sezgin Model
Chanju Kim, Yoonbai Kim, O-Kab Kwon
We study DBI-type effective theory of an unstable D3-brane in the background manifold R^{1,1} x M_2 where M_2 is an arbitrary two-dimensional manifold. We obtain an exact tubular D…
Unstable D-branes and String Cosmology
Chanju Kim, Hang Bae Kim, Yoonbai Kim +2
Cosmological implication of rolling tachyons is reported in the context of effective field theory. With a brief review of rolling tachyons in both flat and curved spacetimes, we st…
