Martedì 15 Aprile 2014, ore 12:00 - Aula 1BC45 - Anatoly Neishtadt



Martedì 15 Aprile 2014 alle ore 12:00 in aula 1BC45, il prof. Anatoly Neishtadt (Mosca e Loughborough) terrà un seminario dal
titolo "On mechanisms of destruction of adiabatic invariance".

In many problems of classical mechanics and theoretical physics dynamics can be described as a slow evolution of some periodic or quasi-periodic processes. Adiabatic invariants are approximate conservation laws for such systems. Existence of adiabatic invariants makes dynamics close to regular. Destruction of adiabatic invariance leads to chaotic dynamics. In the talk it is planned to present a review of currently known mechanisms of destruction of adiabatic invariance. It is planned to consider examples of manifestation of these mechanisms in problems related to charged particles dynamics.
