Abstract

There are two results in the literature that seem closely related: Padmanabhan’s interpretation of field equations near a null surface as a thermodynamic identity and Jacobson’s derivation of Einstein equations from the Clausius relation of thermodynamics. I compare and contrast these two results in the framework of Gaussian null coordinates near a null surface.
