Asymptotic Freedom in a Scalar Field Theory on the Lattice
An alternative model to the trivial φ4-theory of the standard model of weak interactions is suggested, which embodies the Higgs-mechanism, but is free of the conceptual problems of standard φ4-theory. We propose a N -component, O(N)-symmetric scalar field theory, which is originally defined on the lattice. The model can be motivated from SU(2) gauge theory. Thereby the scalar field arises as a ...
متن کاملThe (φ4)2 Field Theory as a Classical Ising Model
We approximate a (spatially cutoff) (φ4)2 Euclidean field theory by an ensemble of spin 1/2 Ising spins with ferromagnetic pair interactions. This approximation is used to prove a Lee-Yang theorem and GHS type correlation inequalities for the (0 4 ) 2 theory. Application of these results are presented.
متن کاملCritical Magnetic Field and Asymptotic Behavior of Superconducting Thin Films
In this paper, we discuss the vortex structure of the superconducting thin films placed in a magnetic field. The discussion is based on a system of simplified Ginzburg–Landau equations. We obtain the estimate for the lower critical magnetic field Hc1 , in the sense that it is the first critical value of hex, the applied field, for which the minimal energy among vortexless configurations is equa...
متن کاملAsymptotic Freedom and Dirichlet String Theory
Fixed angle scattering at high energy in a string theory with boundaries satisfying Dirichlet conditions (Dirichlet strings) inD = 4 is shown to have logarithmic dependence on energy, in addition to the power-like behavior known before. High temperature free energy also depends logarithmically on temperature. Such a result could provide a matching mechanism between strings at long distance and ...
متن کاملAsymptotic Behavior for Nonlocal Diffusion Equations
We study the asymptotic behavior for nonlocal diffusion models of the form ut = J ∗ u − u in the whole R or in a bounded smooth domain with Dirichlet or Neumann boundary conditions. In R we obtain that the long time behavior of the solutions is determined by the behavior of the Fourier transform of J near the origin, which is linked to the behavior of J at infinity. If Ĵ(ξ) = 1 − A|ξ| + o(|ξ|) ...
