Series Solutions of PT-Symmetric Schrödinger Equations
Chris Ford, Bichang Xia
We consider series solutions of the Schrödinger equation for the Bender-Boettcher potentials V(x)=-(ix)^N with integer N. A simple truncation is introduced which provides accurate…
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…
