Entropic forces have recently attracted considerable attention as ways to reformulate, retrodict, and perhaps even “explain” classical Newtonian gravity from a rather specific thermodynamic perspective. In this article I point out that if one wishes to reformulate classical Newtonian gravity in terms of an entropic force, then the fact that Newtonian gravity is described by a conservative force places significant constraints on the form of the entropy and temperature functions. (These… 

Decoherence-free entropic gravity: Model and experimental tests

Erik Verlinde’s theory of entropic gravity [JHEP 2011, 29 (2011)], postulating that gravity is not a fundamental force but rather emerges thermodynamically, has garnered much attention as a possible

Inconsistencies in Verlinde’s emergent gravity

A bstractWe point out that recent Verlinde’s proposal of emergent gravity suffers from some internal inconsistencies. The main idea in this proposal is to preserve general relativity at short scales

Entropic force approach to noncommutative Schwarzschild black holes signals a failure of current physical ideas

Recently, a new perspective of gravitational-thermodynamic duality as an entropic force arising from alterations in the information associated with the positions of material bodies is found. In this

Cosmological constraints on entropic cosmology with matter creation

We investigate entropic force cosmological models with the possibility of matter creation and energy exchange between the bulk and the horizon of a homogeneous and an isotropic flat Universe. We

Energy equipartition and minimal radius in entropic gravity

In this article, we investigate the assumption of equipartition of energy in arguments for the entropic nature of gravity. It has already been pointed out by other authors that equipartition is not

Some features of the entropic gravity scenario for spherically symmetric solutions derived from f (R) gravity

We try to discuss a model of f (R) gravity with the idea of entropic force, especially for the model that is applied in a broad range of scales, from the Solar System to the cosmological scale. We

Jeans Instability, Jeans Entropy and the Entropy Origin of Gravity

An entropic origin of gravity is re-visited. Isothermal self-gravitating cloud seen as an ideal gas is analyzed. Gravitational attraction within the isothermal cloud in equilibrium is balanced by the

Gravedad emergente: ¿La llave termodinámica del espacio-tiempo?

We consider some aspects of the inciting relation between gravity and thermodynamics and describe how this has led to propose that gravity is not a fundamental interaction, but an emergent phenomenon

Exploring the Nature of Gravity

I clarify the differences between various approaches in the literature which attempt to link gravity and thermodynamics. I then describe a new perspective based on the following features: (1) As in



Is Gravity an Entropic Force?

It is argued that the existence of a minimum size of Spacetime, together with the Heisenberg uncertainty principle in quantum theory, may imply the fundamental existence of gravity as a geometric property of spacetime, and may provide a further support for the conclusion that gravity is not an entropic force.

Coulomb force as an entropic force

Motivated by Verlinde's theory of entropic gravity, we give a tentative explanation to the Coulomb's law with an entropic force. When trying to do this, we find the equipartition rule should be

Gravity is not an entropic force

We argue that experiments with ultra-cold neutrons in the gravitational field of Earth disprove recent speculations on the entropic origin of gravitation. Introduction. Recently, E. Verlinde

Thermodynamical Aspects of Gravity: New insights

The fact that one can associate thermodynamic properties with horizons brings together principles of quantum theory, gravitation and thermodynamics and possibly offers a window to the nature of

Reversible and irreversible spacetime thermodynamics for general Brans-Dicke theories

We derive the equations of motion for Palatini F(R) gravity by applying an entropy balance law TdS={delta}Q+{delta}N to the local Rindler wedge that can be constructed at each point of spacetime.

Nonequilibrium thermodynamics of spacetime: The role of gravitational dissipation

In [T. Jacobson, Phys. Rev. Lett. 75, 1260 (1995).] it was shown that the Einstein equation can be derived as a local constitutive equation for an equilibrium spacetime thermodynamics. More recently,

Analogue Models for Emergent Gravity

Gravity stands out among the fundamental interactions because of its apparent incompatibility with having a quantum description. Moreover, thermodynamic aspects of gravitation theory appears as

Gravity and the Thermodynamics of Horizons


Sakharov's 1967 notion of "induced gravity" is currently enjoying a significant resurgence. The basic idea, originally presented in a very brief 3-page paper with a total of four formulas, is that

Holography in action

The Einstein-Hilbert action and its natural generalizations to higher dimensions (like the Lanczos-Lovelock action) have certain peculiar features. All of them can be separated into a bulk and a
