Constraints on Rindler Hydrodynamics

Understand

We study uncharged Rindler hydrodynamics at second order in the derivative expansion.

• The equation of state of the theory is given by a vanishing equilibrium energy density.
• We derive relations among the transport coefficients by employing two frameworks.
• First, by the requirement of having an entropy current with a non-negative divergence, second by studying the thermal partition function on stationary backgrounds.
