Time delays for attosecond streaking in photoionization of neon

Numerical Simulations of Attosecond Streaking Time Delays in Photoionization

We present results of numerical simulations and theoretical classical analysis of time delays with respect to the instant of ionization in a numerical streaking experiment. These results confirm our previous interpretation of the streaking time delay as a finite-range and fieldweighted time delay. We show that in the streaking experiments the time delay strongly depends on the parameters of the...

Finite-range time delays in numerical attosecond-streaking experiments

We present results of numerical simulations and theoretical classical analysis of time delays with respect to the instant of ionization in a numerical streaking experiment. We show that the time delay is related to a finite range in space, which the emitted electron probes after its transition into the continuum until the streaking pulse ceases. This finite-range time delay results from the cou...

Attosecond-streaking time delays: Finite-range property and comparison of classical and quantum approaches

We theoretically study time delays obtained using the attosecond-streaking technique. To this end, we compute time delays by numerically solving the corresponding time-dependent Schrödinger equation and analyze the delays using two classical methods, namely, a perturbative approach and a full numerical solution of Newton’s equation describing the motion of the photoelectron in the continuum. A ...

Photoionization time delays

The material presented in this chapter is based on important advances realized in “attophysics” which make feasible to follow the motion of electrons in atoms and molecules with attosecond-level time resolution. In this context, timedelays have been recently determined in the process of photoionization by extremeultra-violet (xuv) pulses and the question of the significance of these measured de...
