Lectures
Willem Boutu
Laboratoire Interactions, Dynamiques et Lasers (LIDYL), Université Paris-Saclay, CEA, France
High-order harmonic generation in solids
Seminar: "Shaping High Order Harmonic Emission from Crystals in Space and Time"
Willem Boutu is a research director at CEA Paris Saclay, at the LIDYL laboratory. He received his doctoral degree in 2007 in Attophysics from University Paris Sud in the group of Bertrand Carré at CEA Saclay. After a two year postdoctoral stay at the University of California, Berkeley, with Profs. Stephen Leone and Daniel Neumark, he came back to CEA, where he holds a permanent position since 2011. After studying electron dynamics in the gas phase, he recently shifted his interest to the study of strong field physics in the condensed phase. At the same time, he was moved towards a more applied approach to his research, which led to the development of EUV microscopy, a technique which allows to image matter at scales of a few tens of nanometers on a relatively small and simple setup. Since 2020, he leads a joint laboratory with a French SME to develop applications to EUV metrology.

Nonlinear light-matter interaction
Seminar: "Generation and Application of Attosecond-Pulse Trains"
Anne Harth received her doctoral degree (2013, Leibniz University Hannover) under the supervision of Prof. Uwe Morgner on non-collinear optical parametric chirped-pulse amplification techniques and few-cycle laser pulses. During her postdoctoral work with Prof. Anne L’Huillier (Lund University, Sweden) she studied the generation of attosecond pulse trains under tight focussing conditions and participated in experiments applying the method of reconstruction of attosecond beating by interference of two-photon transitions (RABBITT). At the division “Quantum Dynamics and Control”, directed by Prof. Thomas Pfeifer (Max-Planck Institute for Nuclear Physics, Heidelberg), she started a junior research group focussing on multi-photon transitions, expanding the RABBITT technique by combining unconventional colour fields. Since 2021, she is Professor at Aalen University and belongs to the research centre “Zentrum für Optische Technologien”. Her research interests include the fundamentals of nonlinear interactions of ultra-short pulses with various transparent materials and their time dependence.
Time-resolved ARPES: visualising the ultrafast evolution of electronic bands in solids
Seminar: Interplay of topology and correlations in the dynamics of quantum materials
Marino Marsi is professor at Paris-Saclay University, and a specialist in the electronic properties and ultrafast dynamics of quantum materials. He obtained a Ph.D. at the University of Wisconsin-Madison, and after a post-doctoral position at the Ecole Polytechnique Fédérale de Lausanne, he joined the Elettra laboratory in Trieste as a research scientist. In 2005 he was appointed full professor at the Laboratoire de Physique des Solides in Orsay, where he established a research group working on the study of quantum materials, using laser or synchrotron based experimental methods, mainly ultrafast photoemission. His interest rang from transient out-of-equilibrium topological states of matter to the study of phase separation and photoinduced phase transitions in correlated materials. He is recipient of the 2021 Friedel-Volterra award of the SFP and SIF.
