Abstract:
A quantum description of the evolution of atomic states of fast projectiles traveling through matter is presented. Our approach is based on the solution of a quantum Langevin equation, i.e., a time-dependent Schrodinger equation which describes electronic excitations of atoms or ions under the influence of the dynamically screened deterministic potential of the projectile and a stochastic force simulating the dissipative interaction with the solid. We present applications to the stripping of relativistic H- and the population dynamics of electronic substates of 13.6 MeV/u Ar17+ ions by transmission through carbon foils. We analyze the correspondence between classical and quantum transport simulations and we show that the stochastic nature of the interaction destroys most quantum effects.
