Soliton Solutions in Noncritical String Field Theory?

Abstract

We look for soliton solutions in $c=0$ noncritical string field theory constructed by the authors and collaborators. It is shown that the string field action itself is very complicated in our formalism but it satisfies a very simple equation. We derive an equation which a solution to the equation of motion should satisfy. Using this equation, we conjecture the form of a soliton solution which is responsible for the nonperturbative effects of order $e^{-A/κ}$.
