Fermions in a Global Monopole Background

Hai Ren

We study the scattering of fermions in a ``global monopole'' background metric. This is the four-dimensional analogue of the scattering on a cone in three dimensions. The scatterin…

wormholes and topological charge

S. Alexander Ridgway

I investigate solutions to the Euclidean Einstein-matter field equations with topology in a theory with a massless periodic scalar field and electromagnet…

Radiation from a moving Scalar Source

Hai Ren, Erick J. Weinberg

We study classical radiation and quantum bremsstrahlung effect of a moving point scalar source. Our classical analysis provides another example of resolving a well-known apparent p…

Vortex Dynamics in Selfdual Maxwell-Higgs Systems with Uniform Background Electric Charge Density

Ki-Myeong Lee

We introduce selfdual Maxwell-Higgs systems with uniform background electric charge density and show that the selfdual equations satisfied by topological vortices can be reduced to…

Anomaly Cancellation in 2+1 dimensions in the presence of a domainwall mass

Shailesh Chandrasekharan

A Fermion in 2+1 dimensions, with a mass function which depends on one spatial coordinate and passes through a zero ( a domain wall mass), is considered. In this model, originally…

Self-Intersection, Axial Anomaly and the String Picture of QCD

Ravit Efraty

The leading, planar diagrams of the expansion and the usual string description suggest that quarks propagate on the boundary of a two-dimensional world surface. We restrict…

Monopole Vector Spherical Harmonics

Erick J. Weinberg

Eigenfunctions of total angular momentum for a charged vector field interacting with a magnetic monopole are constructed and their properties studied. In general, these eigenfuncti…

Momentum Analyticity and Finiteness of the 1-Loop Superstring Amplitude

Eric D'Hoker, D. H. Phong

The Type II Superstring amplitude to 1-loop order is given by an integral of -functions over the moduli space of tori, which diverges for real momenta. We construct the…

The Dual Formulation of Cosmic Strings and Vortices

Kimyeong Lee

We study four dimensional systems of global, axionic and local strings. By using the path integral formalism, we derive the dual formulation of these systems, where Goldstone boson…

On the Electromagnetic Interactions of Anyons

Chihong Chou, V. P. Nair, A. Polychronakos

Using the appropriate representation of the Poincare group and a definition of minimal coupling, we discuss some aspects of the electromagnetic interactions of charged anyons. In a…
