Fermion Zero Modes for Abelian BPS Monopoles

Bobby Cheng, Chris Ford

Fermion zero modes for abelian BPS monopoles are considered. In the spherically symmetric case the normalisable zero modes are determined for arbitrary monopole charge N. If N>1 th…

Electric-Magnetic Duality in Massless QED?

Chris Ford

The possibility that QED and recently developed non-Hermitian, or magnetic, versions of QED are equivalent is considered. Under this duality the Hamiltonians and anomalous axial cu…

A Causal Algebra for Liouville Exponentials

Chris Ford, George Jorjadze

A causal Poisson bracket algebra for Liouville exponentials on a cylinder is derived using an exchange algebra for free fields describing the in and out asymptotics. The causal alg…

Doubly Periodic Instanton Zero Modes

Chris Ford, Jan M. Pawlowski

Fermionic zero modes associated with doubly periodic SU(2) instantons of unit charge are considered. In cases where the action density exhibits two `instanton cores' the zero mode…

Constituents of Doubly Periodic Instantons

Chris Ford, Jan M. Pawlowski

Using the Nahm transform we investigate doubly periodic charge one SU(2) instantons with radial symmetry. Two special points where the Nahm zero modes have softer singularities are…

Causal Poisson Brackets of the SL(2,R) WZNW Model and its Coset Theories

C. Ford, G. Jorjadze, G. Weigt

From the basic chiral and anti-chiral Poisson bracket algebra of the SL(2,R) WZNW model, non-equal time Poisson brackets are derived. Through Hamiltonian reduction we deduce the co…
