Abstract

We consider the fate of 1/N expansions in unstable many-body quantum systems, as realized by a quench across criticality, and show the emergence of exp(2λt)/N as a renormalized parameter ruling the quantum-classical transition and accounting nonperturbatively for the local divergence rate λ of mean-field solutions. In terms of exp(2λt)/N, quasiclassical expansions of paradigmatic examples of ...
