Renormalized Effective Actions in Radially Symmetric Backgrounds: Exact Calculations Versus Approximation Methods
Gerald V. Dunne, Jin Hur, Choonkyu Lee +1
Our previously-developed calculational method (the partial wave cutoff method) is employed to evaluate explicitly scalar one-loop effective actions in a class of radially symmetric…
Functional Determinants in Quantum Field Theory
Gerald V. Dunne
Functional determinants of differential operators play a prominent role in theoretical and mathematical physics, and in particular in quantum field theory. They are, however, diffi…
Worldline Approach to Chiral Fermions
Kurt Langfeld, Gerald Dunne, Holger Gies +1
We propose to apply ``worldline numerics'' to a numerical calculation of quark determinants. The Gross-Neveu model with a U(1) chiral symmetry is considered as a first test. The wo…
Manipulating atoms in an optical lattice: Fractional fermion number and its optical quantum measurement
J. Ruostekoski, J. Javanainen, G. V. Dunne
We provide a detailed analysis of our previously proposed scheme [Phys. Rev. Lett. 88, 180401, (2002)] to engineer the profile of the hopping amplitudes for atomic gases in a 1D op…
