Boundary States for the Rolling D-branes in NS5 Background
Yu Nakayama, Yuji Sugawara, Hiromitsu Takayanagi
In this paper we construct the time dependent boundary states describing the ``rolling D-brane solutions'' in the NS5 background discovered recently by Kutasov by means of the clas…
Boundary States for Supertubes in Flat Spacetime and Godel Universe
Hiromitsu Takayanagi
We construct boundary states for supertubes in the flat spacetime. The T-dual objects of supertubes are moving spiral D1-branes (D-helices). Since we can obtain these D-helices fro…
Boundary States for D-branes with Traveling Waves
Yasuaki Hikida, Hiromitsu Takayanagi, Tadashi Takayanagi
We construct boundary states for D-branes which carry traveling waves in the covariant formalism. We compute their vacuum amplitudes to investigate their interactions. In non-compa…
Notes on Giant Gravitons on PP-waves
Hiromitsu Takayanagi, Tadashi Takayanagi
We investigate the giant gravitons in the maximally supersymmetric IIB pp-wave from several viewpoints: (i) the dynamics of D3-branes, (ii) the world-sheet description and (iii) th…
Open Strings in Exactly Solvable Model of Curved Spacetime and PP-Wave Limit
Hiromitsu Takayanagi, Tadashi Takayanagi
In this paper we study the superstring version of the exactly solvable string model constructed by Russo and Tseytlin. This model represents superstring theory in a curved spacetim…
