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…
