Abstract: (arXiv)
Recently, a class of gravitational backgrounds in 3+1 dimensions have been proposed as holographic duals to a Lifshitz theory describing critical phenomena in 2+1 dimensions with critical exponent z1z\geq 1. We continue our earlier work \cite{Bertoldi:2009vn}, exploring the thermodynamic properties of the 'black brane' solutions with horizon topology R2\mathbb{R}^2. We find that the black branes satisfy the relation E=22+zTs\mathcal{E}=\frac{2}{2+z}Ts where E\mathcal{E} is the energy density, TT is the temperature, and ss is the entropy density. This matches the expected behavior for a 2+1 dimensional theory with a scaling symmetry (x1,x2)λ(x1,x2)(x_1,x_2)\to \lambda (x_1,x_2), tλztt\to \lambda^z t.
