Exact WKB in all sectors I: Potentials with degenerate saddles
Tatsuhiro Misumi, Cihan Pazarbaşı
We explore the exact-WKB (EWKB) method through the analysis of Airy and Weber types, with an emphasis on the exact quantization of locally harmonic potentials in multiple sectors.…
Cluster expansion and resurgence in Polyakov model
Cihan Pazarbaşı, Mithat Ünsal
In Polyakov model, a non-perturbative mass gap is formed at leading order semi-classics by instanton effects. By using the notions of critical points at infinity, cluster expansion…
Recursive Generation of The Semi-Classical Expansion in Arbitrary Dimension
Cihan Pazarbaşı
We present a recursive procedure, which is based on the small time expansion of the propagator, in order to generate a semi-classical expansion of the \textit{quantum action} for a…
Renormalons in quantum mechanics
Cihan Pazarbasi, Dieter Van den Bleeken
We present a nonrelativistic one-particle quantum mechanics whose perturbative S-matrix exhibits a renormalon divergence that we explicitely compute. The potential of our model is…
