Finite size effects in classical string solutions of the Schrodinger geometry

Abstract

We study finite size corrections to the semiclassical string solutions of the Schrodinger spacetime. We compute the leading order exponential corrections to the infinite size dispersion relation of the single spin giant magnon and of the single spin single spike solutions. The solutions live in a $S^3$ subspace of the five-sphere and extent in the Schrodinger part of the metric. In the limit of zero deformation the finite size dispersion relations flow to the undeformed $AdS_5 \times S^5$ counterparts and in the infinite size limit the correction term vanishes and the known infinite size dispersion relations are obtained.
