Simplified Vacuum Energy Expressions for Radial Backgrounds and Domain Walls
Gerald Dunne, Klaus Kirsten
We extend our previous results of simplified expressions for functional determinants for radial Schrödinger operators to the computation of vacuum energy, or mass corrections, for…
Giving up the ghost
Carl M. Bender, Philip D. Mannheim
The Pais-Uhlenbeck model is a quantum theory described by a higher-derivative field equation. It has been believed for many years that this model possesses ghost states (quantum st…
Dynamically assisted Schwinger mechanism
Ralf Schützhold, Holger Gies, Gerald Dunne
We study electron-positron pair creation {from} the Dirac vacuum induced by a strong and slowly varying electric field (Schwinger effect) which is superimposed by a weak and rapidl…
A Twisted Kink Crystal in the Chiral Gross-Neveu model
Gokce Basar, Gerald V. Dunne
We present the detailed properties of a self-consistent crystalline chiral condensate in the massless chiral Gross-Neveu model. We show that a suitable ansatz for the Gorkov resolv…
Self-consistent crystalline condensate in chiral Gross-Neveu and Bogoliubov-de Gennes systems
Gokce Basar, Gerald V. Dunne
We derive a new exact self-consistent crystalline condensate in the 1+1 dimensional chiral Gross-Neveu model. This also yields a new exact crystalline solution for the one dimensio…
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…
