A singular one-parameter family of solutions in cubic superstring field theory
arXiv:1602.00059 · doi:10.1007/JHEP05(2016)013
Abstract
Performing a gauge transformation of a simple identity-like solution of superstring field theory, we construct a one-parameter family of solutions, and by evaluating the energy associated to this family, we show that for most of the values of the parameter the solution represents the tachyon vacuum, except for two isolated singular points where the solution becomes the perturbative vacuum and the half brane solution.
