Abstract
The population dynamics induced in an atomic system by XUV-attosecond radiation have been investigated within the electric dipole approximation. The main characteristics of the dynamics are explained in simple terms, extending our previous work on coherent laser-atom interactions in the XUV spectral region. Attosecond beating appearing in a second-order autocorrelation of a coherent superposition of high order harmonics, is investigated from the perspective of a superposition of Rabi oscillations, as well as of coherent population return (CPR). The work reveals the strength of attosecond radiation as a tool for time domain studies of coherent manipulations of quantum systems.

In a n-order autocorrelation, the signal, e.g., ionization signal, is obtained as a function of the delay τ between the exciting laser pulses. Thus, we can write Signal\((\tau)\varpropto\int_{-\infty}^{+\infty}{\rm System}(E_1(t), E_2(t+\tau))dt\), where Ei is the electric field of the exciting pulses
