Title: 
The relativistic fluid dual to vacuum Einstein gravity
Abstract: 

We present a construction of a (d+2)-dimensional Ricci-flat metric corresponding to a (d+1)-dimensional relativistic fluid, representing holographically the hydrodynamic regime of a (putative) dual theory. The metric is obtained using a relativistic gradient expansion. The entire dynamics to second order in gradients is encoded in one first order and six second order transport coefficients, which we compute. We classify entropy currents with non-negative divergence at second order in relativistic gradients and compute holographically an entropy current associated with the bulk solution. We discuss novel Lagrangian models which realize key properties of the holographic fluid.
