A remark on Chebyshev rational functions, multipoint Padé approximants and Noise
Maxim Derevyagin, Max Meynig
Motivated by the recent interest in multipoint Padé approximants in the physics community, we discuss Chebyshev rational functions and show how they give rise to multipoint Padé ap…
Non-perturbative asymptotics of the eigenvalues of the spheroidal equation
Max Meynig
New non-perturbative results on the eigenvalues of the spheroidal equation are presented. The results, found using an all orders WKB analysis, include a perturbative/non-perturbati…
Generating and Computing Quantum Periods in Exact WKB
Max Meynig
Periods of rational integrals appear in quantum mechanics through asymptotic expansions of traces computed with the semiclassical symbol calculus. We develop a novel formal series…
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…
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…
Semiclassical Trans-Series from the Perturbative Hopf-Algebraic Dyson-Schwinger Equations: QFT in 6 Dimensions
Michael Borinsky, Gerald V. Dunne, Max Meynig
We analyze the asymptotically free massless scalar quantum field theory in 6 dimensions, using resurgent asymptotic analysis to find the trans-series solutions which yield th…
Odd Harmonics in Exoplanet Photometry: Weather or Artifact?
Nicolas B. Cowan, Victoria Chayes, Elie Bouffard +2
Photometry of short-period planetary systems allows astronomers to monitor exoplanets, their host stars, and their mutual interactions. In addition to the transits of a planet in f…
