چکیده
We study stability of the Dynamical Fixed Points (DFPs) cascading gauge theory at strong coupling in de Sitter space-time. compute spectra perturbative fluctuations and identify stable/unstable DFPs, characterized by ratio scale $\Lambda$ Hubble constant $H$ background discover a new phenomenon spectrum gravitational non-conformal holographic model: distinct branches for $H\gg \Lambda$ coalesce sufficiently low $\frac{H}{\Lambda}$, leading to removal some excited modes from spectrum. establish that, least dual supergravity approximation, does not have stable DFP $H\in (H_{crit_1},H_{crit_2})$. Initial states $H>H_{crit_2}$ evolve with unbroken chiral symmetry; while $H< H_{crit_1}$ vacuum spontaneously broken symmetry.

de Sitter Gravity from Lattice Gauge Theory
We investigate a lattice model for Euclidean quantum gravity based on discretization of the Palatini formulation of General Relativity. Using Monte Carlo simulation we show that while a naive approach fails to lead to a vacuum state consistent with the emergence of classical spacetime, this problem may be evaded if the lattice action is supplemented by an appropriate counter term. In this new m...
متن کاملThe Case for a Gravitational de Sitter Gauge Theory
With the exception of gravitation, the known fundamental interactions of Nature are mediated by gauge fields. A comparison of the candidate groups for a gauge theory possibly describing gravitation favours the Poincaré group as the obvious choice. This theory gives Einstein’s equations in a particular case, and Newton’s law in the static non-relativistic limit, being seemingly sound at the clas...
متن کاملAnti-de Sitter space from supersymmetric gauge theory
We construct a four dimensional Yang-Mills theory with N = 4 twisted supersymmetry whose classical vacua correspond to four dimensional anti-de Sitter space. The theory utilizes a complex gauge field whose real part is a spin connection which is used to enforce local Lorentz invariance. The imaginary part of the connection can then be interpreted as a vierbein. The topological construction ensu...
متن کاملThe semiclassical stability of de Sitter spacetime
de Sitter spacetime and Bunch-Davies vacuum are a solution to the semiclassical Einstein-Schrödinger equations describing the evolution of spacetime geometry and a massive scalar quantum field with arbitrary coupling to curvature. The stability of this solution is proven by calculating the renormalized energy momentum tensor expectation value for small spatially homogeneous deviations from the ...
متن کاملGauge-gravity correspondence in de Sitter braneworld
We study the braneworld solutions based on a solvable model of 5d gauged supergravity with two scalars of conformal dimension three, which correspond to bilinear operators of fermions in the dual N = 4 super Yang-Mills theory on the boundary. An accelerating braneworld solution is obtained when both scalars are taken as the form of deformations of the super Yang-Mills theory and the bulk supers...
