Tachyon solutions in boundary and cubic string field theory
We construct rolling tachyon solutions of cubic and boundary string field theory (CSFT and BSFT, respectively), in the bosonic and supersymmetric (susy) case. A solution of susy CSFT is presented, together with a family of time-dependent BSFT solutions for the bosonic and susy string. These are parametrized by an arbitrary constant r involved in solving the Green equation of the target fields. ...
متن کاملTachyon Kinks in Boundary String Field Theory
We study tachyon kinks with and without electromagnetic fields in the context of boundary string field theory. For the case of pure tachyon only an array of kinkantikink is obtained. In the presence of electromagnetic coupling, all possible static codimension-one soliton solutions such as array of kink-antikink, single topological BPS kink, bounce, half kink, as well as nonBPS topological kink ...
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 کاملTachyon Condensation and Universal Solutions in String Field Theory
We investigate a non-perturbative vacuum in open string field theory expanded around the analytic classical solution which has been found in the universal Fock space generated by matter Virasoro generators and ghost oscillators. We carry out level-truncation analyses up to level (6, 18) in the theory around one-parameter families of the solution. We observe that the value of the vacuum energy a...
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...
