<p><font face="Arial, Helvetica, sans-serif" size="2">Resonant capture is an important paradigm in nonlinear physics with applications in planetary dynamics, plasmas, fluids, nonlinear waves, etc. A particle trapped in a potential well and driven by a chirped frequency perturbation comprises a simplest manifestation of this paradigm. A sharp threshold on the driving amplitude for capture into resonance is characteristic of the case when the trapped particle starts in equilibrium. In the presence of a weak noise or a small temperature (T) initial distribution of trapped particles, the threshold develops a width, scaling as T<sup>0.5</sup>. I will explain this unusual scaling and show that counter-intuitively, addition of repulsive self-fields in the case of an ensemble of trapped charged particles (non-neutral plasmas) makes the width of the resonant transition narrower.</font></p> <p><span style="FONT-WEIGHT: 700"><font face="Arial, Helvetica, sans-serif" color="#697da9" size="2"><a href="" target="_blank">Get the flier...</a></font></span></p><SPAN STYLE="display: none"> <P>Acetylenide minutes, pointedly?
