Resurgence of the Effective Action in Inhomogeneous Fields
Gerald V. Dunne, Zachary Harris
We show how background field inhomogeneities modify the non-perturbative structure of the effective action. The simple Borel poles of the Euler-Heisenberg effective action become b…
Entropy Suppression through Quantum Interference in Electric Pulses
Gerald V. Dunne, Adrien Florio, Dmitri E. Kharzeev
The Schwinger process in strong electric fields creates particles and antiparticles that are entangled. The entropy of entanglement between particles and antiparticles has been fou…
Noise Effects on Pade Approximants and Conformal Maps
Ovidiu Costin, Gerald V. Dunne, Max Meynig
We analyze the properties of Pade and conformal map approximants for functions with branch points, in the situation where the expansion coefficients are only known with finite prec…
Uniformizing Lee-Yang Singularities
Gokce Basar, Gerald Dunne, Zelong Yin
Motivated by the search for the QCD critical point, we discuss how to obtain the singular behavior of a thermodynamic system near a critical point, namely the Lee-Yang singularitie…
Instantons or Renormalons? A Comment on phi4_4 Theory in the MS Scheme
Gerald V. Dunne, Max Meynig
We comment that the recent exact six-loop and seven-loop computations of renormalization group functions for the O(N)-symmetric four dimensional phi^4 quantum field theory show hin…
Borel Summation and Analytic Continuation of the Heat Kernel on Hyperbolic Space
Gerald V. Dunne
The heat kernel expansion on even-dimensional hyperbolic spaces is asymptotic at both short and long times, with interestingly different Borel properties for these short and long t…
