1. On the physical parametrization and magnetic analogs of the Emparan–Teo dihole solution

Abstract

Abstract: The Emparan–Teo non-extremal black dihole solution is reparametrized using Komar quantities and the separation distance as arbitrary parameters. We show how the potential can be calculated for the magnetic analogs of this solution in the Einstein–Maxwell and Einstein–Maxwell-dilaton theories. We also demonstrate that, similar to the extreme case, the external magnetic field can remove the supporting strut in the non-extremal black dihole too. [Copyright &y& Elsevier]

2. On the time-dependent Aharonov–Bohm effect

Abstract

The Aharonov–Bohm effect in the background of a time-dependent vector potential is re-examined for both non-relativistic and relativistic cases. Based on the solutions to the Schrodinger and Dirac equations which contain the time-dependent magnetic vector potential, we find that contrary to the conclusions in a recent paper (Singleton and Vagenas 2013 [4] ), the interference pattern will be altered with respect to time because of the time-dependent vector potential.

3. Charge definition in non-abelian gauge theories

Author

Stanley Deser and L. F. Abbott

Subjects
Physics, Nuclear and High Energy Physics, Introduction to gauge theory, High Energy Physics::Lattice, High Energy Physics::Phenomenology, Magnetic monopole, Charge (physics), High Energy Physics::Theory, Theoretical physics, Dyon, Supersymmetric gauge theory, Quantum electrodynamics, Magnetic potential, Mathematical descriptions of the electromagnetic field, Gauge fixing
Abstract

Conserved gauge-invariant electric and magnetic charges are defined for non-abelian gauge theories in terms of the asymptotic symmetries of the field configurations. They are expressed as flux integrals. Illustrations include the magnetic charge of the 't Hooft-Polyakov monopole and the electric and magnetic charges of the Julia-Zee dyon.

4. Non-uniqueness of the source for singular gauge fields

Abstract

We show that the singular Wu-Yang solution for SU(2) gauge fields may be interpreted as due to a point source at the origin. However, the electric or magnetic nature of the source depends on whether one approaches the singularity by means of a “smeared” potential or a “smeared” field strength.
