Classical string solutions in non-relativistic AdS5 × S5: closed and twisted sectors

Abstract

We find classical closed string solutions to the non-relativistic AdS5 × S5 string theory which are the analogue of the BMN and GKP solutions for the relativistic theory. We show that non-relativistic AdS5 × S5 string theory admits a orbifold symmetry which allows us to impose twisted boundary conditions. Among the solutions in the twisted sector, we find the one around which the semiclassical expansion in arXiv:2102.00008 takes place.
