[en] Non-Abelian vortices of the type proposed by Nielsen and Olesen are discussed. It is
shown that the vortices must contain a single unit of quantized flux absorbed by a Dirac …

Vortex states of photons, electrons, and other particles are non-plane-wave solutions of the
corresponding wave equation with helicoidal wave fronts. These states possess an intrinsic …

Structured light refers to the generation and application of custom light fields. As the tools
and technology to create and detect structured light have evolved, steadily the applications …

The Quantum Theory of Fields, first published in 1996, is a self-contained, comprehensive
introduction to quantum field theory from Nobel Laureate Steven Weinberg. Volume II gives …

A unified field theory of mesons and their particle sources is proposed and considered in its
classical aspects. The theory has static solutions of a singular nature, but finite energy …

This is the fourth, expanded edition of the comprehensive textbook published in 1990 on the
theory and applications of path integrals. It is the first book to explicitly solve path integrals of …

Abstract Particles beyond the Standard Model (SM) can generically have lifetimes that are
long compared to SM particles at the weak scale. When produced at experiments such as …

It is obvious that such a string cannot break since we canrı ot have an end point: it is
impossible to replace a rotation C ver 2 conti–nuously by n (p)-1. Or: magnetic monopoles …

Through an examination of the Bohm-Aharonov experiment an intrinsic and complete
description of electromagnetism in a space-time region is formulated in terms of a …

First published in 1956, this classic work by NF Ramsey, 1989 Nobel Laureate in Physics,
provides an account of atomic and molecular structure. After an introductory section …
