Renormalized Effective Actions in Radially Symmetric Backgrounds I: Partial Wave Cutoff Method
Gerald V. Dunne, Jin Hur, Choonkyu Lee
The computation of the one-loop effective action in a radially symmetric background can be reduced to a sum over partial-wave contributions, each of which is the logarithm of an ap…
Closed-form weak-field expansion of two-loop Euler-Heisenberg Lagrangians
G. V. Dunne, A. Huet, D. Rivera +1
We obtain closed-form expressions, in terms of the Faulhaber numbers, for the weak-field expansion coefficients of the two-loop Euler-Heisenberg effective Lagrangians in a magnetic…
Multidimensional Worldline Instantons
Gerald V. Dunne, Qing-hai Wang
We extend the worldline instanton technique to compute the vacuum pair production rate for spatially inhomogeneous electric background fields, with the spatial inhomogeneity being…
Large-order Perturbation Theory and de Sitter/Anti de Sitter Effective Actions
Ashok Das, Gerald V. Dunne
We analyze the large-order behavior of the perturbative weak-field expansion of the effective Lagrangian density of a massive scalar in de Sitter and anti de Sitter space, and show…
Functional determinants for radial operators
Gerald V. Dunne, Klaus Kirsten
We derive simple new expressions, in various dimensions, for the functional determinant of a radially separable partial differential operator, thereby generalizing the one-dimensio…
Fluctuations about Cosmological Instantons
Gerald V. Dunne, Qing-hai Wang
We study the semiclassical fluctuation problem around bounce solutions for a self-interacting scalar field in curved space. As in flat space, the fluctuation problem separates into…
