The Tully-Fisher's law and Dark Matter effects derived via modified symmetries
Ivan Arraut
In any physical system, when we move from short to large scales, new spacetime symmetries emerge which help us to simplify the dynamics of the system. In this letter we demonstrate…
Vacuum degeneracy in Massive gravity=Multiplicity of fundamental scales
Ivan Arraut, Kaddour Chelabi
The presence of Nambu-Goldstone bosons introduce a natural degeneracy inside the vacuum solutions of the non-linear formulations of massive gravity in the same spirit of the -mo…
The graviton Higgs mechanism
Ivan Arraut
The Higgs mechanism at the graviton level formulated as a Vainshtein mechanism in time domains implies that the extra-degrees of freedom become relevant depending on the direction…
The dynamical origin of the graviton mass in the non-linear theory of massive gravity
Ivan Arraut
We compare the standard Higgs mechanism corresponding to the scalar field, with the dynamical origin of the graviton mass inside the scenario of the dRGT theory of massive gravity.…
The Vainshtein conditions: The Vainshtein mechanism in terms of Stückelberg functions
Ivan Arraut
Here I develop the simplest method in order to evaluate whether or not the Vainshtein mechanism can operate for a given set of parameters in a given solution. The method is based o…
Path-integral derivation of black-hole radiance inside the de-Rham-Gabadadze-Tolley formulation of massive gravity
Ivan Arraut
If we apply the path integral formulation in order to analyze the particle creation process of black-holes inside the non-linear formulation of massive gravity, it is possible to d…
The Black Hole Radiation in Massive Gravity
Ivan Arraut
We apply the Bogoliubov transformations in order to connect two different vacuums, one~located at past infinity and another located at future infinity around a black hole inside th…
The Komar mass function in the de-Rham-Gabadadze-Tolley non-linear theory of massive gravity
Ivan Arraut
I derive the Komar mass/function for the Schwarszchild de-Sitter (S-dS) black-hole inside the dRGT non-linear theory of massive gravity by taking the usual notion of time-like Kill…
On the apparent loss of predictability inside the de-Rham-Gabadadze-Tolley non-linear formulation of massive gravity: The Hawking radiation effect
Ivan Arraut
I explain in a simple and compact form the origin of the apparent loss of predictability inside the dRGT non-linear formulation of massive gravity. This apparent pathology was firs…
Can a non-local model of gravity reproduce Dark Matter effects in agreement with MOND?
Ivan Arraut
I analyze the possibility of reproducing MONDian Dark Matter effects by using a non-local model of gravity. The model was used before in order to recreate screening effects for the…
On the Black Holes in alternative theories of gravity: The case of non-linear massive gravity
Ivan Arraut
I derive general conditions in order to explain the origin of the Vainshtein radius inside dRGT. The set of equations, which I have called "Vainshtein" conditions are extremal cond…
The Astrophysical Scales Set by the Cosmological Constant, Black-Hole Thermodynamics and Non-Linear Massive Gravity
Ivan Arraut
We calculate explicitly the black-hole temperature for the Schwarzschild de-Sitter solution inside massive gravity by defining the Killing-vector in the direction of the Stückelber…
Relative locality and relative Co-locality as extensions of the Generalized Uncertainty Principle
Ivan Arraut
I introduce the spatial curvature effects inside the formalism of Relative Locality as a non-commutative structure of the momentum space in agreement with the very well known conce…
The Planck length as a duality of the Cosmological Constant: S-dS and S-AdS thermodynamics from a single expression
Ivan Arraut
In this paper we suggest that the Planck length and the Cosmological Constant scale could in principle be dual each other if we take seriously the s…
About the propagation of the Gravitational Waves in an asymptotically de-Sitter space: Comparing two points of view
Ivan Arraut
We analyze the propagation of gravitational waves (GWs) in an asymptotically de-Sitter space by expanding the perturbation around Minkowski and introducing the effects of the Cosmo…
Velocity and velocity bounds in static spherically symmetric metrics
I. Arraut, D. Batic, M. Nowakowski
We find simple expressions for velocity of massless particles in dependence of the distance in Schwarzschild coordinates. For massive particles these expressions put an upper b…
The Minimum and Maximum Temperature of Black Body Radiation
M. Nowakowski, I. Arraut
We show, in different ways, that in the ubiquitous phenomenon of black body radiation there exists a minimum and maximum temperature. These limiting values are so small and large r…
Comparing two approaches to Hawking radiation of Schwarzschild-de Sitter black holes
I. Arraut, D. Batic, M. Nowakowski
We study two different ways to analyze the Hawking evaporation of a Schwarzschild-de Sitter black hole. The first one uses the standard approach of surface gravity evaluated at the…
The fate of a gravitational wave in de Sitter spacetime
M. Nowakowski, I. Arraut
If we want to explain the recently discovered accelerated stage of the universe, one of the option we have is to modify the Einstein tensor. The simplest such modification, in agre…
