QED Effective Actions in Inhomogeneous Backgrounds: Summing the Derivative Expansion
Gerald V. Dunne
The QED effective action encodes nonlinear interactions due to quantum vacuum polarization effects. While much is known for the special case of electrons in a constant electromagne…
Calorons in Weyl Gauge
Gerald V. Dunne, Bayram Tekin
We demonstrate by explicit construction that while the untwisted Harrington-Shepard caloron is manifestly periodic in Euclidean time, with period , when transf…
Dynamical Localization of Gravity
Aharon Davidson, Philip D. Mannheim
We show that the thin wall limit of the thick domain wall associated with a sine-Gordon soliton in a single non-compactified patch of 5-dimensional spacetime explicitly yields the…
Deconfining Phase Transition in 2+1 D: the Georgi-Glashow Model
Gerald Dunne, Ian I. Kogan, Alex Kovner +1
We analyze the finite temperature deconfining phase transition in 2+1 dimensional Georgi-Glashow model. We show explicitly that the transition is due to the restoration of the magn…
Two-loop corrections to the topological mass term in thermal QED_3
F. T. Brandt, Ashok Das, J. Frenkel +1
We study the radiative corrections to the Chern-Simons mass term at two loops in 2+1 dimensional quantum electrodynamics at finite temperature. We show that, in contrast to the beh…
Constraints on Embeddings
Philip D. Mannheim
We show that the embedding of either a static or a time dependent maximally 3-symmetric brane with non-zero spatial curvature into a non-compactified bulk does not yiel…
