Rolling of Modulated Tachyon with Gauge Flux and Emergent Fundamental String
Soo-Jong Rey, Shigeki Sugimoto
We investigate real-time tachyon dynamics of unstable D-brane carrying fundamental string charge. We construct the boundary state relevant for rolling of modulated tachyon with gau…

Rolling Tachyon with Electric and Magnetic Fields -- T-duality approach -----
Soo-Jong Rey, Shigeki Sugimoto
We study the decay of unstable D-branes when the world-volume gauge field is turned on. We obtain the relevant Dp-brane boundary state with electric and magnetic fields by boost…

Exact Description of D-branes via Tachyon Condensation
Tsuguhiko Asakawa, Shigeki Sugimoto, Seiji Terashima
We examine the fluctuations around a Dp-brane solution in an unstable D-brane system using boundary states and also boundary string field theory. We show that the fluctuations corr…
