Gravity from Thermodynamics: Going beyond Einstein equation of state

ORAL

Abstract

We will discuss the possibility of deriving the classical equation of motion of any diffeomorphism-invariant theory of gravity from the thermodynamic relation $T\delta S = \delta Q$, applied to a local Rindler horizon with $S$ as the Wald entropy. The approach generalizes an earlier result for General Relativity and thereby suggests a thermodynamic origin of any metric theory of gravity.
