1210.3554 (Zbigniew Ambrozinski et al.)

Resummation of not summable series    [PDF]

Zbigniew Ambrozinski, Jacek Wosiek
In this paper we present results of computations for the ground energy of weakly coupled double well potential in quantum mechanics. We give a numerical evidence for cancelation of imaginary contributions to energy coming from Borel resummation and multi-instanton terms. We also estimate several higher coefficients of the multi-instanton expansion which are not given in the literature.
