N-body Simulations for f(R) Gravity using a Self-adaptive Particle-Mesh Code
N-body Simulations Gravity Self-adaptive Particle-Mesh Code
2010/12/24
We perform high resolution N-body simulations for f(R) gravity based on a self-adaptive particle- mesh code MLAPM. The Chameleon mechanism that recovers General Relativity on small scales is fully ta...
Background independent condensed matter models for quantum gravity
Background independent condensed matter models quantum gravity
2010/12/27
A number of recent proposals for a quantum theory of gravity are based on the idea that spacetime geometry and gravity are derivative concepts and only apply at an approximate level. There are two fu...
Three of the four forces of Nature are described by quantum Yang-Mills theories with remarkable precision. The fourth force, gravity, is described classically by the Einstein-Hilbert theory. There app...
The Conformal Constraint in Canonical Quantum Gravity
The Conformal Constraint Canonical Quantum Gravity
2010/12/24
Perturbative canonical quantum gravity is considered, when coupled to a renormalizable model for matter fields. It is proposed that the functional integral over the dilaton field should be disentangle...
Fitting galactic rotation curves with conformal gravity and a global quadratic potential
Fitting galactic rotation curves conformal gravity quadratic potential
2010/12/27
We apply the conformal gravity theory to a sample of 110 spiral galaxies whose rotation curve data points extend well beyond the optical disk. With no free parameters other than galactic mass to ligh...
Observational constraints on Chaplygin cosmology in a braneworld scenario with induced gravity and curvature effect
Observational constraints Chaplygin cosmology braneworld scenario
2010/12/27
We study cosmological dynamics and late-time evolution of an extended induced gravity braneworld scenario. In this scenario, curvature effects are taken into account via the Gauss-Bonnet term in the ...
Neutrino oscillation phase dynamically induced by f(R)-gravity
Neutrino mass and mixing Non-standard-model neutrinos Modified theories of gravity
2010/3/18
The gravitational phase shift of neutrino oscillation can be discussed in the framework of f(R)-gravity. We show that the shift of quantum mechanical phase can depend on the given f(R)-theory that we ...
A useful guide for gravitational wave observers to test modified gravity models
gravitational wave modified gravity models
2010/3/17
We present an extension of a previously suggested test of all modified theories of gravity that would reproduce MOND at low accelerations. In a class of models, called "dark matter emulators", gravita...
Nonminimal Inflation on the Randall-Sundrum II Brane with Induced Gravity
Inflation Braneworld Scenario Scalar-Tensor Theories
2010/3/17
We study an inflation model that inflaton field is non-minimally coupled to the induced scalar curvature on the Randall-Sundrum (RS) II brane. We investigate the effects of the non-minimal coupling on...
We calculate modifications to the Schwarzschild solution by using a semiclassical analysis of loop quantum black hole. We obtain a metric inside the event horizon that coincides with the Schwarzschild...
