Worldsheet Description of Tachyon Condensation in Open String Theory
Tadaoki Uesugi
In this thesis we review the fundamental framework of boundary string field theory (BSFT) and apply it to the tachyon condensation on non-BPS systems in the superstring theory. The…
Flux Stabilization of D-branes in NSNS Melvin Background
Tadashi Takayanagi, Tadaoki Uesugi
In this paper we reexamine the D-brane spectrum in the Melvin background with nonconstant NSNS B-field from the viewpoint of its world-volume and string world-sheet theory. We find…
D-branes in Melvin Background
Tadashi Takayanagi, Tadaoki Uesugi
In this paper we discuss D-branes in the Melvin background and its supersymmetric generalizations. In particular we determine the D-brane spectra in these backgrounds by constructi…
Orbifolds as Melvin Geometry
Tadashi Takayanagi, Tadaoki Uesugi
In this paper we explicitly show that the various noncompact abelian orbifolds are realized as special limits of parameters in type II (NSNS) Melvin background and its higher dimen…
On the Supersymmetry of Non-BPS D-brane
Seiji Terashima, Tadaoki Uesugi
In this paper we extend the boundary string field theory action for a non-BPS D-brane to the one including the target space fermions and the nonlinear supersymmetry with 32 superch…
Brane-Antibrane Action from Boundary String Field Theory
Tadashi Takayanagi, Seiji Terashima, Tadaoki Uesugi
In this paper we give the boundary string field theory description of brane-antibrane systems. From the world-sheet action of brane-antibrane systems we obtain the tachyon potentia…
Boundary State Description of Tachyon Condensation
Michihiro Naka, Tadashi Takayanagi, Tadaoki Uesugi
We construct the explicit boundary state description of the vortex-type (codimension two) tachyon condensation in brane-antibrane systems generalizing the known result of the kink-…
