We propose a model for $N$-band superconductors where the phase differences between gaps are represented by abelian gauge fields. This model corresponds to an $SU(N)$ gauge theory with the abelian projection. We show that there are massless modes as well as massive modes when the number of...
The concept of gauge field is a cornerstone of modern physics and the synthetic gauge field has emerged as a new way to manipulate particles in many disciplines. In optics, several schemes of Abelian synthetic gauge fields have been proposed. Here, we introduce a new platform for realizing synt...
阿贝尔P群分类迭代1954年Kaplansky证明了可数约化阿贝尔p群可以用Ulm-Kaplansky不变量来分类,1975年,Warfield把这结果推广到单表现模。本文引入一个所谓抽象的迭代系统,依此系统可以构建一个约化阿贝尔p群,并证明了等价的迭代系统和约化阿贝尔p群的同构类存在着一一对应的关系,从而对约化阿贝尔p群作出了分类。
We consider an Einstein-Hilbert-dilaton action for gravity coupled to various types of Abelian and non-Abelian gauge fields in a spatially finite system. T... JDE Creighton,RB Mann - 《Physical Review D Particles & Fields》 被引量: 208发表: 1995年 Double field formulation of Yang-Mills the...
Inflationary models are usually based on dynamics of one or more scalar fields coupled to gravity. In this work we present a new class of inflationary models, gauge-flation or non-Abelian gauge field inflation, where slow-roll inflation is driven by a non-Abelian gauge field. This class of ...
A simple criterion for Lorentz invariance in quantum field theory is stated as a commutator condition relating the energy density to the momentum density. With its aid a relativistically invariant radiation-gauge formulation is devised for a non-Abelian vector-gauge field coupled to a spin-½ ...
The question is raised for non-Abelian vector gauge fields whether gauge invariance necessarily implies a massless physical particle. As a preliminary to studying this problem, the action principle is used to discover the independent dynamical variables of such gauge fields and construct their ...

Non-Abelian gauge fields1 provide a conceptual framework to describe particles having spins, underlying many phenomena in electrodynamics, condensed-matter physics2,3 and particle physics4,5. Lattice models6 of non-Abelian gauge fields allow us to unders
Non-Abelian gauge fields couple the motional states of the particles to their internal degrees of freedom (such as hyperfine states for atoms or ions, electronic spins for electrons, etc). In this sense external non-Abelian fields extend the concept of spin–orbit coupling (Rashba and ...
