We review the properties of BPS, or supersymmetric, magnetic monopoles, with an
emphasis on their low-energy dynamics and their classical and quantum bound states. After …

It is shown that the global charges of a gauge theory may yield a nontrivial central extension
of the asymptotic symmetry algebra already at the classical level. This is done by studying …

Classical solutions play an important role in quantum field theory, high-energy physics and
cosmology. Real-time soliton solutions give rise to particles, such as magnetic monopoles …

How is it possible to justify a lengthy review of the physics of the magnetic monopole when
nobody has ever seen one? fin spite of the unfortunate lack of favorable experimental …

We study nonabelian vortices (flux tubes) in SU (N) gauge theories, which are responsible
for the confinement of (nonabelian) magnetic monopoles. In particular a detailed analysis is …

We study exponentiated soft exchange in (d+ 2)-dimensional gauge and gravitational
theories using the celestial conformal field theory formalism. These models exhibit …

A charge operator is constructed for a quantum field theory with an abelian discrete gauge
symmetry, and a non-local order parameter is formulated that specifies how the gauge …

This book is an introduction to the role of topology in the quantization of classical systems. It
is also an introduction to topological solitons with special emphasis on Skyrmions. As …

The equations of motion of an isospin-carrying particle in a Yang–Mills and gravitational
field were first proposed in 1968 by Kerner, who considered geodesics in a Kaluza–Klein …

In this volume, topics are drawn from field theory, especially gauge field theory, as applied to
particle, condensed matter and gravitational physics, and concern a variety of interesting …
