Super String Field Theory

   One of the main motivations to construct string field theory (SFT) - an off-shell formulation of a string theory - is a possibility to study non-perturbative phenomena in string theory.

   We study:

 1.  Tachyon condensation in cubic NS SFT.

 2.  NS SFT around new vacuum - vacuum SSFT.

 3. Solutions to vacuum SSFT.

 4. Time-dependence solutions to NS SFT.
