Analytical solutions of pure-spinor superstring field theory
  We examine the possibility of constructing analytical solutions describing marginal deformations in the open superstring field theory that is based on the non-minimal pure-spinor formalism. It is found out that some methods used for constructing solutions of bosonic and RNS string field theories do not seem to generalize to the pure-spinor case, while other methods do lead to reliable analytical solutions.
