Quantum Stability of the Phase Transition in Rigid QED
M. Awada, D. Zoller, J. F. Clark
Rigid QED is a renormalizable generalization of Feynman's space-time action characterized by the addition of the curvature of the world line (rigidity). We have recently shown that…

Phase Transition and Absence Of Ghosts in Rigid QED
Moustafa Awada, David Zoller
Ordinary QED formulated in the Feynman's space-time picture is equivalent to a one dimensional field theory. In the large N limit there is no phase transition in such a theory. In…

Phase Transition in Rigid String Coupled to Kalb-Ramond Fields
Moustafa Awada, David Zoller
Polyakov has argued that the QCD string should have long range order. We show that a phase transition does exist in a generalization of string theory characterized by the addition…
