摘要：
The shear viscosity, eta, of a fermi gas with non-relativistic conformal symmetry in two spatial dimensions is investigated. We find that eta/s, s being the entropy density, diverges as a gas of free particles in this system. This is in contrast to the eta/s = 1/4 pi found using the non-relativistic AdS/CFT correspondence, which requires a strongly interacting CFT. It implies that the unitary fermi gas in two spatial dimensions is not likely to have a weakly interacting gravity dual.
