Giant magnonlike solution in Sch(5) x S-5

Abstract

In this paper we derive a giant magnonlike solution for a string theory in a Schrodinger spacetime Sch(5) x S-5 which is holographic dual to a dipole-deformed super-Yang-Mills theory. This classical string state is pointlike in Sch(5) but stringy in a S-2 subspace of S-5. We find the string solution and the energy-charge relation exactly for an infinite angular momentum as well as for a finite one which shows an explicit finite-size correction.
