Comments on Schnabl’s analytic solution for tachyon condensation in Witten’s open string field theory
Schnabl recently constructed an analytic solution for tachyon condensation in Witten’s open string field theory. The solution consists of two pieces. Only the first piece is involved in proving that the solution satisfies the equation of motion when contracted with any state in the Fock space. On the other hand, both pieces contribute in evaluating the kinetic term to reproduce the value predic...
متن کاملTachyon Condensation and Open String Field theory
We perform canonical quantization of the open string on a unstable D-brane in the background of the tachyon condensation. Evaluating the Polyakov path-integral on a stripe, we obtain the field theoretical propagator in the open string theory. As the condensation occurs the string field theory is continuously deformed. At the infrared fixed point of the condensation, the open string field on the...
متن کاملGauge Invariance and Tachyon Condensation in Open String Field Theory
The gauge invariance of open string field theory is considered from the point of view of level truncation, and applications to the tachyon condensation problem are discussed. We show that the region of validity of Feynman-Siegel gauge can be accurately determined using the level truncation method. We then show that singularities previously found in the tachyon effective potential are gauge arti...
متن کاملLight-like tachyon condensation in Open String Field Theory
We use open string field theory to study the dynamics of unstable branes in the bosonic string theory, in the background of a generic linear dilaton. We find a simple exact solution describing a dynamical interpolation between the perturbative vacuum and the recently discovered nonperturbative tachyon vacuum. In our solution, the open string tachyon increases exponentially along a null directio...
متن کاملA Review on Tachyon Condensation in Open String Field Theories
We review the recent studies of tachyon condensation in string field theory. After introducing the open string field theory both for bosonic string and for superstring, we use them to examine the conjecture that the unstable configurations of the D-brane will decay into the ‘closed string vacuum’ through the tachyon condensation. And we describe the attemps to construct a lower dimensional boso...
