Nonperturbative effects - Open Access .click

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1984
Abstract A theoretical investigation of ion-induced inner-shell ionization is described, in which some physical effects that are nonperturbative in nature are included within the formalism of perturbation theory. In particular, the effects of the dynamical response of the outer electrons under the influence of the incident projectile are considered ...

Nonperturbative effects at small x

Nuclear Physics B - Proceedings Supplements, 1991
Abstract A review of existing data shows the importance of nonperturbative contributions, particularly to those structure functions that vary rapidly with χ. The connection between small χ behaviour and the rise with energy of total hadronic cross sections requires the presence of a term χ −1.085 rather than the conventional χ −1 .

Dynamic Franz–Keldysh effect: perturbative to nonperturbative regime

Optics Letters, 2000
We study theoretically the dynamic Franz-Keldysh effect for quantum wells excited by a cw optical field and a terahertz (THz) frequency driving field. By monitoring the THz sidebands one can show that for, increasing THz-field amplitudes, nonperturbative effects become predominant, and one must account for THz-field-induced nonlinearities to all orders.
