Generalized Einstein’s Equations from Wald Entropy We derive the gravitational equations of motion of general theories of gravity from thermodynamics applied to a local Rindler horizon through any point in spacetime. Specifically, for a given theory of gravity, we substitute the corresponding Wald entropy into the Clausius relation. Our approach works for all diffeomorphism-invariant theories of gravity in which the Lagrangian is a polynomial in the Riemann tensor.ctbParikh, MaulikautSarkar, SudiptactbCollege of Liberal Arts and Scienceseng10.3390/e180401191099-4300https://hdl.handle.net/2286/R.I.431058 pages114926226991623969609128704mogborn1In CopyrightAttribution2016-03-31Text
