STUDIES OF THE QUANTUM DYNAMICS OF RYDBERG ELECTRONS IN SUPERINTENSE LASER FIELDS USING DISCRETE VARIABLE REPRESENTATIONS

摘要: We present calculations on the quantum dynamics of Rydberg states in intense laser fields using a new discrete variable representation adapted to Coulomb problem obtain time-dependent wavefunction. have observed stabilization against ionization regimes approximately predicted by ponderomotive energy criterion Pont and Shakeshaft. analyzed our wavefunctions terms bound continuum field-free hydrogen atom, find clear evidence that is associated with excitation very high states, which are stable ionization, thereby trapping population.
