The boundary state from open string fields
Michael Kiermaier, Yuji Okawa, Barton Zwiebach
We construct a class of BRST-invariant closed string states for any classical solution of open string field theory. The closed string state is a nonlinear functional of the open st…
Real analytic solutions for marginal deformations in open superstring field theory
Yuji Okawa
We construct analytic solutions for marginal deformations satisfying the reality condition in open superstring field theory formulated by Berkovits when operator products made of t…
Analytic Solutions for Marginal Deformations in Open String Field Theory
Michael Kiermaier, Yuji Okawa, Leonardo Rastelli +1
We develop a calculable analytic approach to marginal deformations in open string field theory using wedge states with operator insertions. For marginal operators with regular oper…
Energy-momentum Tensors in Matrix Theory and in Noncommutative Gauge Theories
Yuji Okawa, Hirosi Ooguri
The energy-momentum tensor of Matrix Theory is derived by computing disk amplitudes with one closed string and an arbitrary number of open strings and by taking the DKPS limit. We…
