Deformations of holographic duals to non-relativistic CFTs

We construct the non-relativistic counterparts of some well-known supergravity solutions dual to relevant and marginal deformations of N = 4 super Yang-Mills. The main tool we use is the null Melvin twist and we apply it to the N = 1 and N = 2* Pilch-Warner RG flow solutions as well as the Lunin-Maldacena solution dual to beta-deformations of N = 4 super Yang-Mills. We also obtain a family of supergravity solutions with Schrodinger symmetry interpolating between the non-relativistic version of the N = 1 Pilch-Warner and Klebanov-Witten fixed points. A generic feature of these non-relativistic backgrounds is the presence of non-vanishing internal fluxes. We also find the most general, three-parameter, null Melvin twist of the AdS(5) x S-5 black hole. We briefly comment on the field theories dual to these supergravity solutions.
