Dynamics of Gravity as Thermodynamics on the Spherical Holographic Screen

TL;DR

This paper demonstrates that the dynamics of Lovelock gravity can be interpreted as a thermodynamic process on any spherical holographic screen, extending the thermodynamic view of gravity beyond horizons.

Contribution

It shows that gravity's dynamics on spherical screens can be formulated as a generalized first law of thermodynamics, supporting a broader thermodynamic interpretation of gravity.

Findings

Gravity dynamics on spherical screens can be expressed as a thermodynamic law.

Temperature and entropy are consistent on general spherical screens.

Thermodynamic interpretation applies beyond black hole horizons.

Abstract

The dynamics of general Lovelock gravity, viewed on an arbitrary spherically symmetric surface as a holographic screen, is recast as the form of some generalized first law of thermodynamics on the screen. From this observation together with other two distinct aspects, where exactly the same temperature and entropy on the screen arise, it is argued that the thermodynamic interpretation of gravity is physically meaningful not only on the horizon, but also on a general spherically symmetric screen.
