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.

QCD Running Coupling in the Nonperturbative and Near-Perturbative Regimes.

Physical Review Letters
We use analytic continuation to extend the gauge-gravity duality nonperturbative description of the strong force coupling into the transition, near-perturbative, regime where perturbative effects become important.

Nonperturbative effects in matrix models and D-branes

, 2003
The large order growth of string perturbation theory in c ≤ 1 conformal field theory coupled to world sheet gravity implies the presence of O(e-1/gs) non-perturbative effects, whose leading behavior can be calculated in the matrix model approach ...

Perturbation theory and nonperturbative effects: A happy marriage ?

Czechoslovak Journal of Physics, 1992
Perturbation expansions in renormalized quantum field theories are reformulated in a way that permits a straightforward handling of situations when in the conventional approach, i.e. in fixed renormalization scheme, these expansions are factorially divergent and even of asymptotically constant sign.
