DOI: 10.1007/jhep02(2019)151
Abstract: A bstractIn this work, a clear connection is made between E. Verlinde’s recent theory of emergent gravity in de Sitter space [1], and the earlier work describing emergent gravity using holographic screens [2]. A modified… read more here.

DOI: 10.1007/jhep11(2017)007
Abstract: 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 where numerous tests verified its… read more here.

DOI: 10.1007/s10714-018-2382-4
Abstract: Recently, a new interesting idea of origin of gravity has been developed by Verlinde. In this scheme of emergent gravity, where horizon entropy, microscopic de Sitter states and relevant contribution to gravity are involved, an… read more here.

DOI: 10.1103/physrevd.102.084007
Abstract: We use a sample of 23 galaxy clusters to test the predictions of emergent gravity (EG) as alternative to dark matter. Our sample has both weak-lensing inferred total mass profiles as well as x-ray inferred… read more here.

DOI: 10.1103/physrevd.95.064019
Abstract: It was recently proposed that the effects usually attributed to particle dark matter on galaxy scales are due to the displacement of dark energy by baryonic matter, a paradigm known as emergent gravity. This formalism… read more here.

DOI: 10.1103/physrevd.96.108501
Abstract: Following recent Verlinde's heuristic construction or emergent gravity, Hossenfelder wrote down the Lagrangian capturing some aspects of this theory. We point out that there is an error in calculations whose consequence is that a cosmological… read more here.

DOI: 10.1103/physrevd.98.024041
Abstract: We consider a theory of scalars minimally coupled to an auxiliary background metric. The theory is generally covariant and subject to the constraint of vanishing energy-momentum tensor. Eliminating the auxiliary metric leads to a reparametrization… read more here.

DOI: 10.3390/app11188763
Abstract: One of the main problems that emergent-gravity approaches face is explaining how a system that does not contain gauge symmetries ab initio might develop them effectively in some regime. We review a mechanism introduced by… read more here.
