  • Chaotic ionization of a stationary electron state via a phase space turnstile 

    Burke, Korana; Mitchell, Kevin A.; Ye, Shuzhen; Dunning, F. Barry (2013)
    The ionization of a highly excited Rydberg atom subjected to a periodic sequence of electric field impulses, or “kicks,” is chaotic. We focus on the dynamics of a single kicking period in order to isolate the ionization ...
