nonperturbative effect

C19055
concept

A nonperturbative effect is a physical phenomenon that cannot be captured by any finite-order expansion in a small parameter (such as a coupling constant) and instead arises from intrinsically non-linear or exponentially suppressed contributions, like instantons or tunneling.
