Large-order Perturbation Theory for a Non-Hermitian PT-symmetric Hamiltonian
Carl M. Bender, Gerald V. Dunne
A precise calculation of the ground-state energy of the complex PT-symmetric Hamiltonian , is performed using high-order Rayleigh-Schrödinger perturbation th…
Complex periodic potentials with real band spectra
Carl M. Bender, Gerald V. Dunne, Peter N. Meisinger
This paper demonstrates that complex PT-symmetric periodic potentials possess real band spectra. However, there are significant qualitative differences in the band structure for th…
On the QED Effective Action in Time Dependent Electric Backgrounds
Gerald Dunne, Theodore Hall
We apply the resolvent technique to the computation of the QED effective action in time dependent electric field backgrounds. The effective action has both real and imaginary parts…
Comment on ``Non-thermalizability of a Quantum Field Theory''
S. Deser, G. Dunne, L. Griguolo +3
We point out that the claims made in the paper ``Non-thermalizability of a Quantum Field Theory'' (hep-th/9802008) by C. R. Hagen are irrelevant to our recent results concerning la…
