“…For MG theories, the simulations incorporate the coupling of the density field to a scalar field such as f R for f (R) models. A number of papers have reported simulations that include such a coupling for both f (R) and DGP gravity [395,[395][396][397][398][1000][1001][1002].…”

“…Two essential products from simulations are the nonlinear mass power spectrum and the mass function of galaxy and cluster sized halos [395,397,398,[1000][1001][1002][1003]. For specific models these predictions allow for comparisons to data.…”

Functions of other curvature invariants have also been considered [406][407][408][409][410], but f (R) theories are distinguished in that they (and f (Gauss-Bonnet) theories) do not have ghosts.…”

Beyond the cosmological standard model

After a decade and a half of research motivated by the accelerating universe, theory and experiment have a reached a certain level of maturity. The development of theoretical models beyond Λ or smooth dark energy, often called modified gravity, has led to broader insights into a path forward, and a host of observational and experimental tests have been developed. In this review we present the current state of the field and describe a framework for anticipating developments in the next decade. We identify the guiding principles for rigorous and consistent modifications of the standard model, and discuss the prospects for empirical tests.We begin by reviewing recent attempts to consistently modify Einstein gravity in the infrared, focusing on the notion that additional degrees of freedom introduced by the modification must "screen" themselves from local tests of gravity. We categorize screening mechanisms into three broad classes: mechanisms which become active in regions of high Newtonian potential, those in which first derivatives of the field become important, and those for which second derivatives of the field are important. Examples of the first class, such as f (R) gravity, employ the familiar chameleon or symmetron mechanisms, whereas examples of the last class are galileon and massive gravity theories, employing the Vainshtein mechanism. In each case, we describe the theories as effective theories and discuss prospects for completion in a more fundamental theory. We describe experimental tests of each class of theories, summarizing laboratory and solar system tests and describing in some detail astrophysical and cosmological tests. Finally, we discuss prospects for future tests which will be sensitive to different signatures of new physics in the gravitational sector.The review is structured so that those parts that are more relevant to theorists vs. observers/experimentalists are clearly indicated, in the hope that this will serve as a useful reference for both audiences, as well as helping those interested in bridging the gap between them.

We use 1-dimensional numerical simulations to study spherical collapse in the f (R) gravity models. We include the nonlinear self-coupling of the scalar field in the theory and use a relaxation scheme to follow the collapse. We find an unusual enhancement in density near the virial radius which may provide observable tests of gravity. We also use the estimated collapse time to calculate the critical overdensity δ c used in calculating the mass function and bias of halos. We find that analytical approximations previously used in the literature do not capture the complexity of nonlinear spherical collapse. PACS numbers: 98.65.Dx,95.36.+x,04.50.-h * Electronic address:
