Four lectures on analytic solutions in open string field theory

TThe following notes derive from review lectures on the subject of analytic solutions in open string field theory, given at the School for String Field Theory and String Phenomenology at the Haris...

String field representation of the Virasoro algebra

We construct a representation of the zero central charge Virasoro algebra using string fields in Witten's open bosonic string field theory. This construction is used to explore extensions of the KBc algebra and fin...

On multibrane solutions in open string field theory

Existence of open string field theory solutions describing configurations of multiple space-filling D-branes has been a subject of numerous speculations for quite some time. In this talk we present some new results giving f...

Light-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 proving that the true tachyon vacuum o...

EXACT SOLUTIONS OF OPEN BOSONIC STRING FIELD THEORY

In this paper we present two solutions of open bosonic string field theory defined on D0-brane background that correspond to the change of the D0-brane position in the transverse space....

String field theory solution for any open string background

We present an exact solution of open bosonic string field theory which can be used to describe any time-independent open string background. The solution of this kind can describe nearly any open <...

Topological defects in open string field theory

We show how conformal field theory topological defects can relate solutions of open string field theory for different boundary conditions. To this end we generalize the results of Graham and Watts to include the ac...

String field theory solution for any open string background. Part II

Generalizing previous work, we give a new analytic solution in Witten’s open bosonic string field theory which can describe any open string background. The central idea is to use Riemann surface degenerati...

Deriving on-shell open string field amplitudes without using Feynman rules

We present a series of new gauge-invariant quantities in Witten's open string field theory. They are defined for a given set of open string states which satisfy the physical state condition around a classi...

The phantom term in open string field theory

We show that given any two classical solutions in open string field theory and a singular gauge transformation relating them, it is possible to write the second solution as a gauge transformation of the first plus a singula...
