Tachyon condensation using the disc partition function
Justin R. David
It has been recently proposed that the background independent open superstring field theory action is given by the disc partition function with all possible open string operators i…
Tachyon condensation in the D0/D4 system
Justin R. David
The D0/D4 system with a Neveu-Schwarz B-field in the spatial directions of the D4-brane has a tachyon in the spectrum of the (0,4) strings. The tachyon signals the instability of t…
U(1) gauge invariance from open string field theory
Justin R. David
The naive low energy effective action of the tachyon and the U(1) gauge field obtained from string field theory does not correspond to the world volume action of unstable branes in…
Infra-red dynamics of D1-branes at the conifold
Justin R. David
We study the infra-red dynamics of D1-branes at the conifold. We show using methods developed to study the infra-red dynamics of (4,4) theories, the infra-red degrees of freedom of…
