Motivated in part by string theory, we consider a modification of the {lambda}CDM cosmological model in which the dark matter has a long-range scalar force screened by light particles. Scalar forces can have interesting effects on structure formation: the main example presented here is the expulsion of dark matter halos from low density regions, or voids, in the galaxy distribution.

How to simulate the Universe in a box? Testing modified gravity with a N-body simulation code.

In this paper we present preliminary results from cosmological simulations of modified gravity in the dark matter sector. Our results show improvements over standard cold dark matter cosmology. The

Boosting hierarchical structure formation with scalar-interacting dark matter

We investigate the effect of long-range scalar interaction s in dark matter (DM) models of cosmic structure formation with a particular focus on the formation times of haloes. Utilising N -body

Bose–Einstein condensation, dark matter and acoustic peaks

Scalar mediated interactions among baryons extend well above the Compton wavelength, when they are embedded in a Bose–Einstein condensate composed of the mediating particles. Indeed, this non-trivial

Structure formation in a string-inspired modification of the cold dark matter model

Motivated in part by string theory, we consider the idea that the standard {lambda}CDM cosmological model might be modified by the effect of a long-range scalar dark matter interaction. The variant

Constraining Interactions in Cosmology's Dark Sector

We consider the cosmological constraints on theories in which there exists a nontrivial coupling between the dark matter sector and the sector responsible for the acceleration of the universe, in

Dark Matter Gravitational Clustering With a Long-Range Scalar Interaction

We explore the possibility of improving the {lambda}CDM model at megaparsec scales by introducing a scalar interaction that increases the mutual gravitational attraction of dark matter particles.

Primordial dark matter halos from fifth forces

We argue that primordial dark matter halos could be generated during radiation domination by long-range attractive forces stronger than gravity. In this paper, we derive the conditions under which

Hydrodynamical N-body simulations of coupled dark energy cosmologies

If the accelerated expansion of the Universe at the present epoch is driven by a dark energy scalar field, there may well be a non-trivial coupling between the dark energy and the cold dark matter

Galactic halos in cosmology with long‐range scalar DM interaction

Based on a set of cosmological N‐body simulations we analyze properties of the dark matter (DM) haloes in a galaxy mass range (1011–1013 h‐1Modot) in modified ΛCDM cosmology with additional

Interacting Dark Matter and Dark Energy

We discuss models for the cosmological dark sector in which the energy density of a scalar field approximates Einstein's cosmological constant and the scalar field value determines the dark matter

Scalar self-interactions loosen constraints from fifth force searches

The mass of a scalar field mediating a fifth force is tightly constrained by experiments. We show, however, that adding a quartic self-interaction for such a scalar makes most tests much less

It is predicted that near-future satellite experiments could measure an effective Newton's constant in space different from that on Earth, as well as violations of the equivalence principle stronger than currently allowed by laboratory experiments.

We use numerical simulations to examine the substructure within galactic and cluster mass halos that form within a hierarchical universe. Clusters are easily reproduced with a steep mass spectrum of
