Non-relativistic hydrodynamics

Non-relativistic generalization of the original AdS/CFT correspondence has opened up new directions in current research after a series of beautiful experiments on cold atoms at unitarity. The correspondence has been extended to explore the holographic duals of strongly coupled non-relativistic conformal field theories. Cold atoms are system of fermions inter- acting through a short-range potential which can be fine-tuned to obtain a massless bound state. Since the theory is scale invariant, it can be described as a non-relativistic conformal field theory with Schr ̈odinger symmetry. This symmetry consists of the usual Galilean invariance, the scaling symmetry as well as the particle number symmetry. There has been some activity along this direction where solution generating techniques have been used to obtain bulk geometries with asymptotic Schr ̈odinger symmetry.
