Adiabatic Passage through Chaos

We study the process of nonlinear stimulated Raman adiabatic passage within a classical mean-field framework. Contrary to the prevailing dogma, the breakdown of adiabaticity in the interacting non-integrable system, is not related to bifurcations in the energy landscape, but rather to the emergence of quasi-stochastic motion that drains the followed quasi-stationary state. Consequently, faster sweep rate, rather than quasi-static variation of parameters, is better for adiabaticity.
