Quantum evolution of atomic states during transmission through solids

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 influ...
