Tutorial 2: Wednesday 18 May 2016, 16.45 - 19.30pm, HPF G6

Tutorial Number 1: Atomic Photoionization with Applications to Harmonic Generation and Multiphoton Ionization
Starace Tutorial Lecture 1 (14.11 MB)

Abstract: I will review basic features of atomic photoionization [1,2] and then illustrate how knowledge of atomic photoionization can be employed to interpret and predict features that occur in harmonic generation [3-7] and multiphoton ionization [8, 9].

Tutorial Number 2: Attosecond Physics: Near Future Prospects Starace Tutorial IIa (1.46 MB), Starace Tutorial IIb (6.61 MB)

Abstract: Various experimental groups are aiming to produce isolated, few-cycle attosecond light pulses as well as sub-femtosecond electron pulses.  In this tutorial I will survey some of the new physics that will become possible when these goals are achieved.  Specifically, I will present the theory of attosecond photoionization by few-cycle, carrier-envelope-phase stable attosecond light pulses and then show and discuss the unique features of the predicted ionization spectra produced by such pulses [1-4].  I will then examine reasons why attosecond electron pulses are advantageous for imaging target electronic motion by means of ultrafast electron diffraction (UED), show proof-of-principle calculations illustrating the ability of such pulses to image electronic motion, and discuss the theoretical requirements underlying the ability of UED to image target electronic motions [5-7].
