A Study of Symmetry Restoration at Finite Temperature in the O(4) Model Using Anisotropic Lattices
نویسندگان
چکیده
Results of investigations of the O(4) spin model at finite temperature using anisotropic lattices are presented. In both the large N approximation and the numerical simulations using the Wolff cluster algorithm we find that the ratio of the symmetry restoration temperature TSR to the Higgs mass mH is independent of the anisotropy. We obtain a lower bound of 0.59±0.04 for the ratio, TSR/mH, at mHa ≃ 0.5, which is lowered further by about 10% at mHa ≃ 1.

A Lower Bound on TSR/mH in the O(4) Model on Anisotropic Lattices
Results of an investigation of the O(4) spin model at finite temperature using anisotropic lattices are presented. In both the large N approximation and numerical simulations using the Wolff cluster algorithm we find that the ratio of the symmetry restoration temperature TSR to the Higgs mass mH is independent of the anisotropy ξ. From the numerical simulations we obtain a lower bound of TSR/mH...
متن کاملNoether Symmetry in f(T) Theory at the anisotropic universe
As it is well known, symmetry plays a crucial role in the theoretical physics. On other hand, the Noether symmetry is a useful procedure to select models motivated at a fundamental level, and to discover the exact solution to the given lagrangian. In this work, Noether symmetry in f(T) theory on a spatially homogeneous and anisotropic Bianchi type I universe is considered. We discuss the Lagran...
متن کاملChiral Symmetry Restoration in Anisotropic QED3
We present results from a Monte Carlo simulation of non-compact lattice QED in 3 dimensions in which an explicit anisotropy κ between x and y hopping terms has been introduced into the action. Using a parameter set corresponding to broken chiral symmetry in the isotropic limit κ = 1, we study the chiral condensate on 16, 20, and 24 lattices as κ is varied, and fit the data to an equation of sta...
متن کاملOn the Dynamic Characteristic of Thermoelastic Waves in Thermoelastic Plates with Thermal Relaxation Times
In this paper, analysis for the propagation of general anisotropic media of finite thickness with two thermal relaxation times is studied. Expression of displacements, temperature, thermal stresses, and thermal gradient for most general anisotropic thermoelastic plates of finite thickness are obtained in the analysis. The calculation is then carried forward for slightly more specialized case of...
متن کاملChiral Symmetry Restoration and Deconfinement of Light Mesons at Finite Temperature
Abstract There has been a great deal of interest in understanding the properties of quantum chromodynamics (QCD) for a finite value of the chemical potential and for finite temperature. Studies have been made of the restoration of chiral symmetry in matter and at finite temperature. The phenomenon of deconfinement is also of great interest, with studies of the temperature dependence of the conf...
