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

Worldline instantons and the fluctuation prefactor
TL;DR: Dunne and Schubert as mentioned in this paper presented a direct numerical approach for determining the prefactor arising from quantum fluctuations about the classical closed path in Euclidean spacetime, and they found a simple explicit formula for determining this prefactor in the cases where the inhomogeneous electric field is a function of just one spacetime coordinate.

The Weyssenhoff fluid in Einstein-Cartan theory
TL;DR: In this article, the variational theory of an ideal spinning fluid is developed, which is described by original Weyssenhoff-Raabe tensors of spin and energy-momentum.

Geometric mechanics, Lagrangian reduction, and nonholonomic systems
TL;DR: In this article, the Lagrangian reduction theory of nonholonomic systems with symmetry has been extended to non-holonomic mechanical systems, which provides an intrinsic geometric setting for many of the results that were previously understood primarily in coordinates.
Journal ArticleDOI
Perfect fluid theory and its extensions
TL;DR: In this paper, the authors review the canonical theory for perfect fluids in Euler's and Lagrange's formulations, which is related to a description of extended structures in higher dimensions, including internal symmetry and supersymmetry degrees of freedom.

Electromagnetic effects in the quantum interference of dipoles
Jeeva Anandan,Jeeva Anandan +1 more
TL;DR: In this paper, the phase shift in the interference of a magnetic or electric dipole due to the electromagnetic field is obtained relativistically and non-relativistically, and the force and torque on the particle are obtained in the classical limit.

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.
