Marginal deformations of SU(2) WZW model boundary states in open string field theory
Matěj Kudrna
We attempt to describe the moduli space of boundary states in the SU(2) WZW model by constructing marginally deformed solutions in open string field theory in the level truncat…
Boundary states in the SU(2) WZW model from open string field theory
Matěj Kudrna
We analyze boundary states in the SU(2) WZW model using open string field theory in the level truncation approximation. We develop algorithms that allow effective calculation o…
Level Truncation Approach to Open String Field Theory
Matěj Kudrna
Given a D-brane background in string theory (or equivalently boundary conditions in a two-dimensional conformal field theory), classical solutions of open string field theory equat…
BRST cohomology of timelike Liouville theory
Teresa Bautista, Harold Erbin, Matěj Kudrna
We compute the Hermitian sector of the relative BRST cohomology of the spacelike and timelike Liouville theories with generic real central charge in each case, coupled to a s…
Numerical solution for tachyon vacuum in the Schnabl gauge
E. Aldo Arroyo, Matěj Kudrna
Based on the level truncation scheme, we develop a new numerical method to evaluate the tachyon vacuum solution in the Schnabl gauge up to level . We confirm the prediction t…
Universal Solutions in Open String Field Theory
Matej Kudrna, Martin Schnabl
An outstanding problem in open bosonic string field theory is the existence of nontrivial classical solutions in its universal sector. Such solutions independent of the underlying…
