Exciton in an Aharonov-Bohm ring: An exactly soluble interacting mesoscopic system
(2006)A Green's function procedure leads to an exact determination of the energy spectrum and the associated eigenstates of a system of two oppositely charged particles interacting through a contact potential and moving in a ...

Negative-refractive-index transmission-line metamaterials and enabling electromagnetic applications
(2004)The negative-refractive-index (NRI) metamaterials, for which the permittivity and permeability are simultaneously negative, were discussed. The results for two RF/Microwave devices and structures, based on transmission-line ...

Worldline path integral for the massive Dirac propagator: A four-dimensional approach
(1999)We simplify and generalize an approach proposed by Di Vecchia and Ravndal to describe a massive Dirac particle in external vector and scalar fields. Two different path integral representations for the propagator are derived ...
