Symmetry analysis of reversible Markov chains
Reversible markov chain orbital diagram characteristic vector;the mixture of markov chain an arbitrary number
2015/8/11
We show how to use subgroups of the symmetry group of a reversible Markov chain to give useful bounds on eigenvalues and their multiplicity. We supplement classical representation theoretic tools invo...

Chiral Symmetry and Electroweak pi,K, n Processes
Chiral perturbation theory the low energy electroweak symmetry goldstone boson
2014/12/23
Recently the development of chiral perturbation theory has allowed the generation of rigorous low-energy theorems for various hadronic processes based only on the chiral invariance of the underlying Q...
PHOTON-PHOTON SCATTERING, PION POLARIZABILITY, AND CHIRAL-SYMMETRY
Meson polarizability dispersion relations chiral perturbation theory expert at low amplitude decentralized processing
2014/12/23
Recent attempts to detect the pion polarizability via analysis of γγ→ππ measurements are examined. The connection between calculations based on dispersion relations and on chiral perturbation theory i...
Anthropic considerations in multiple-domain theories and the scale of electroweak symmetry breaking
The standard model quality parameters quantum physical parameter values
2014/12/22
One of the puzzles of the Standard Model is why the mass parameter which determines the scale of the Weak interactions is closer to the scale of Quantum Chromodymanics (QCD) than to the Grand Unificat...

Lagrange differential pv coupling constant the standard model
2014/12/22
We construct the complete SU(2) parity-violating (PV) π,N,Δ interaction Lagrangian with one derivative, and calculate the chiral corrections to the PV Yukawa NNπ coupling constant hπ through O(1/Λχ3) ...

Beyond Spontaneously Broken Symmetry in Bose-Einstein Condensates
Condensate treatment stage bell inequality particles quantum Angle the population oscillation
2014/12/19
Spontaneous symmetry breaking (SSB) for Bose-Einstein condensates cannot treat phase off-diagonal effects, and thus cannot explain Bell inequality violations. We describe another situation that is bey...
GAUGE NON-INVARIANCE AS TESTS OF EMERGENT GAUGE SYMMETRY
Incentives emergency plan is symmetrical the underlying basic theory lorentz invariance of gravity field
2014/12/18
We motivate the concept of emergent gauge symmetry and discuss ways that this concept can be tested. The key idea is that if a symmetry is emergent, one should look for small violations of this symmet...

Hopf bifurcation zero frequency imperfect SO(2) symmetry Dynamical Systems
2012/6/29
Rotating waves are periodic solutions in SO(2) equivariant dynamical systems. Their precession frequency changes with parameters and it may change sign, passing through zero. When this happens, the dy...

2012/6/25
We consider the Dirichlet problem for the nonlinear $p(x)$-Laplacian equation. For axially symmetric domains we prove that, under suitable assumptions, there exist Mountain-pass solutions which exhibi...
