DESCRIPTION:Speaker:  Arnaud Lazarus  (Sorbonne Universite)\n\nTitle: Explo
 iting periodicity in the dynamic stability of systems with time-varying pro
 perties\n\nAbstract:\n\nDynamic stability is the ability of a system’s conf
 igurational state to overcome a disturbance over time. A common way to pass
 ively control this dynamical feature is to periodically modulate the proper
 ties of the system in time. This is what is done to trigger the swings of t
 he Butafumeiro at the Santiago de Compostela Cathedral\, to dynamically sta
 bilize charged particles in mass spectrometers or to sustain exotic quantum
  states in Floquet engineering. \n\nIn this presentation\, we show that new
  dynamical phenomena emerge when the periodic variations of the system’s pr
 operties are large and occur on similar time scales than the natural ones. 
 In this regime\, it becomes straightforward to break the record of super-ha
 rmonic orders observed in the parametric pumping of an oscillator or to dyn
 amically trap a magnetic dipole on its unstable equilibrium thanks to an ov
 erlooked quantum analogy.\n\nAll the shown examples are rationalized throug
 h a fundamental 1 degree-of-freedom model and some desktop-scale experiment
 s but the dynamical concepts being universal\, it should offer new function
 alities across scales and engineering domains.
