Quaternion Spin 2 Field Theory
Abstract In this paper I propose solutions to the nature of Dark matter, Dark energy, Matter and the Matter-Antimatter asymmetry. The real spin representations of a 7d complex space are assumed to be the source of a chiral gauge group SU(8)xU(1) and a spin 2 quaternion field. The integral of the probability density of the spin 2 field results in a lower bound for r and consequently the Schwarzs...
متن کاملEffective field theory approach to gravitationally induced decoherence.
Adopting the viewpoint that the standard perturbative quantization of general relativity provides an effective description of quantum gravity that is valid at ordinary energies, we show that gravity as an environment induces the rapid decoherence of stationary matter superposition states when the energy differences in the superposition exceed the Planck energy scale.
متن کاملGravitationally coupled scale-free discs
In a composite fluid system of two gravitationally coupled barotropic scale-free discs bearing a rotation curve v ∝ r and a power-law surface mass density Σ0 ∝ r −α with α = 1 + 2β, we construct coplanar stationary aligned and spiral perturbation configurations in the two discs. Due to the mutual gravitational interaction, there are two independent classes of perturbation modes with surface mas...
متن کاملSpin in Quantum Field Theory
I introduce spin in field theory by emphasizing the close connection between quantum field theory and quantum mechanics. First, I show that the spin–statistics connection can be derived in quantum mechanics without relativity or field theory. Then, I discuss path integrals for spin without using spinors. Finally, I show how spin can be quantized in a path–integral approach, without introducing ...
متن کاملStrongly coupled quantum field theory
We analyze numerically a two-dimensional λφ theory showing that in the limit of a strong coupling λ → ∞ just the homogeneous solutions for time evolution are relevant in agreement with the duality principle in perturbation theory as presented in [M.Frasca, Phys. Rev. A 58, 3439 (1998)], being negligible the contribution of the spatial varying parts of the dynamical equations. A consequence is t...
