Symmetry breaking in a U(1) extended non-minimal supersymmetric standard model
... First of all we cannot allow the scalar fields carrying electric charge to get vacuum expectation values as this would lead to the breaking of the elec- tromagnetic symmetry. To see how this has consequences for ...

Energy transport in a disordered spin chain with broken U(1) symmetry : diffusion, subdiffusion, and many body localization
... In this paper we investigate the physics of the disor- dered spin-1/2 XYZ chain. We choose this model be- cause it is a quantum spin chain in which all conserva- tion laws are violated except energy. In particular, the ...

Axial U(1) symmetry at high temperature in 2-flavor lattice QCD
... where λ (ov i ,m) is the i-th eigenvalue of the massive overlap Dirac operator, and we set the lattice spacing a = 1. When the GW relation is violated, there are additional terms in Eq. (3) [17]. Eq. (3) includes the e ff ...

LHC signals of the SO(5)×U(1) gauge-Higgs unification
... A Higgs boson has been discovered by LHC experiments. This discovery supports the standard model(SM) as a unified theory of electroweak symmetry. However, the SM does not contain the dark matter and the SM has ...

Nondegeneracy of Solution to the Allen Cahn Equation with Regular Triangle Symmetry
... There have been a lot of work on this equation during the last two decays (see for example [1]-[5] and the references there in). An important class of solutions to (1.1) is the multiple-end solutions. By ...

Potential Symmetry Studies on a Rotating Fluid System
... The symmetries of the rotational fluid model 1.1–1.5 are studied in three ways. Firstly, we directly study the Lie symmetries of the full system 1.1–1.5 for the fields {u, v, p, ρ, w}. The result shows us that the ...
