Field and particle equations for the classical Yang-Mills field and particles with isotopic spin
TLDR
A complete system of equations describing the interaction between the Yang-Mills field and isotopic-spin-carrying particles in the classical limit is extracted from the equations of motion for the quantum fields.Abstract:
A complete system of equations describing the interaction between the Yang-Mills field and isotopic-spin-carrying particles in the classical limit is extracted from the equations of motion for the quantum fields. Some simple consequences are derived. The consistency of the equations is investigated.read more

Particles with non abelian charges
TL;DR: In this paper, the Grassmann variables are used to take into account color degrees of freedom, which are known to produce reducible representations of the color group, and then they couple with a U(1) gauge field defined on the worldline, together with a Chern-Simons term to achieve projection on an irreducible representation.

Classical Yang-Mills observables from amplitudes
TL;DR: In this paper, the authors studied the classical dynamics of colour-charged particle scattering from the perspective of amplitudes, rather than equations of motion, and explained how to compute the change of colour and the radiation of colour, during a classical collision.

Non-Abelian gauge field optics.
Yuntian Chen,Ruo-Yang Zhang,Zhongfei Xiong,Zhi Hong Hang,Jensen Tsan Hang Li,Jian Qi Shen,Che Ting Chan +6 more
TL;DR: Synthetic SU(2) non-Abelian gauge fields in anisotropic media are demonstrated, which allows the study of novel optical phenomena not found in Abelian synthetic gauge field systems.

Constructing phase space distributions with internal symmetries
Niklas Mueller,Raju Venugopalan +1 more
TL;DR: In this paper, an ab initio world-line approach to construct phase space distributions in systems with internal symmetries is discussed. But the results for the Liouville distribution with both spin and color are of interest in fields as diverse as chiral fluids, finite temperature field theory and polarized parton distribution functions.
Journal ArticleDOI
Interference, gravity and gauge fields
TL;DR: In this article, it was shown that there exists a phase shift due to the coupling of spin to space-time curvature, analogous to the Aharonov-Bohm effect.

Conservation of Isotopic Spin and Isotopic Gauge Invariance
Chen Ning Yang,Robert L. Mills +1 more
TL;DR: In this article, it was pointed out that the usual principle of invariance under isotopic spin rotation is not consistant with the concept of localized fields, and the possibility of having invariance in local isotope spin rotations was explored.
