Rayleigh-Ritz Variational Approximation and Symmetry Nonrestoration
The investigation of symmetry nonrestoration scenarios has led to a controversy, with certain nonperturbative approximation schemes giving indications in sharp disagreement with those found within conventional perturbation theory. A Rayleigh-Ritz variational approach to the problem, which might be useful in bridging the gap between perturbative and nonperturbative viewpoints, is here proposed. ...
متن کاملRayleigh-Ritz Approximation and Refinement of Periodic Matrix Pairs
In this paper, we study the Rayleigh-Ritz approximation for the eigenproblem of periodic matrix pairs. We show the convergence of the Ritz value and periodic Ritz vectors. Furthermore, we prove the convergence of refined periodic Ritz vectors and propose an efficient algorithm for computing the refined periodic Ritz vectors. The numerical result shows that the refinement procedure produces an e...
متن کاملHigh Temperature Symmetry Nonrestoration
Naively one expects that at low temperature a system has less symmetry than at high temperature. However, there are cases in nature, where the opposite happens. This phenomenon is called inverse symmetry breaking. A very similar phenomenon is symmetry nonrestoration at high temperature. It appears when the system has at high T less symmetry than allowed by the Lagrangian, which means that some ...
متن کاملRayleigh-Ritz Approximation For the Linear Response Eigenvalue Problem
Large scale eigenvalue computation is about approximating certain invariant subspaces associated with the interested part of the spectrum, and the interested eigenvalues are then extracted from projecting the problem by approximate invariant subspaces into a much smaller eigenvalue problem. In the case of the linear response eigenvalue problem (aka the random phase eigenvalue problem), it is th...
متن کاملSUSY and Symmetry Nonrestoration at High Temperature
The status of internal symmetry breaking at high temperature in supersymmetric models is reviewed. This phenomenon could solve some well known cosmological problems, such as the domain wall, monopole and false vacuum problems.
