Abstract:
We study the behavior of charged particles placed in an Hénon-Heiles type potential, and a circularly polarized laser field. The chaotic behavior is illustrated by calculating the Lyapunov exponent, a general indicator of the presence of chaos in a dynamical system, providing a measure of the average exponential rate of divergence of close orbits. We also study the dependence of the escape time of the particle from the potential, on the laser parameters. Finally, we present a comparison with the results of the quantum approach, obtained by solving the time-dependent Schrodinger equation.
