String Field Theory Around the Tachyon Vacuum
Leonardo Rastelli, Ashoke Sen, Barton Zwiebach
Assuming that around the tachyon vacuum the kinetic term of cubic open string field theory is made purely of ghost operators we are led to gauge invariant actions which manifestly…
Supergravity couplings to Noncommutative Branes, Open Wilson Lines and Generalised Star Products
S. R. Das, S. P. Trivedi
Noncommutative gauge theories can be constructed from ordinary gauge theories in lower dimensions. Using this construction we identify the operators on noncommutative D…
Fundamental Strings in Open String Theory at the Tachyonic Vacuum
Ashoke Sen
We show that the world-volume theory on a D-p-brane at the tachyonic vacuum has solitonic string solutions whose dynamics is governed by the Nambu-Goto action of a string moving in…
Normalization of the Background Independent Open String Field Theory Action
Debashis Ghoshal, Ashoke Sen
It has been shown recently that the background independent open string field theory provides an exact description of the tachyon condensation on unstable D-branes of bosonic string…
Uniqueness of Tachyonic Solitons
Ashoke Sen
It has been conjectured that condensation of tachyons on a bosonic D-brane gives rise to vacuum / soliton solutions which are independent of the initial magnetic field on the D-bra…
Some Issues in Non-commutative Tachyon Condensation
Ashoke Sen
Techniques of non-commutative field theories have proven to be useful in describing D-branes as tachyonic solitons in open string theory. However, this procedure also leads to unwa…
