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…
