An anharmonic alliance: exact WKB meets EPT

Abstract Certain quantum mechanical systems with a discrete spectrum, whose observables are given by a transseries in ħ, were shown to admit ħ 0-deformations with Borel resummable expansions which reproduce the original model at ħ 0 = ħ. Such expansions were dubbed Exact Perturbation Theory (EPT). W...
