Abstract

"The CONQUEST project aims at investigating nonlinear properties of solids by High-order Harmonic Generation (HHG) Spectroscopy. By using a combined experimental and theoretical approach we will unveil the physics
at the micro- and nano-scale of solids irradiated with a strong laser field with unprecedented temporal resolution.
While HHG experiments and models for atoms and molecules are well established, the case of solids is very different. Indeed the initial excitation triggers the formation of multiple interacting electron-hole pairs. This gives
potential access to the formation, relaxation and decay of a wealth of elemental excitations: excitons, bi-excitons, trions, mixed plasmon-exciton states, highly dressed electronic carriers and more.
Experimental results are scarce and numerical approaches rely on simplified models that, devised for atoms and molecules, do not apply to extended materials.
At the same time, extended materials are emerging as prototypes of peculiar physical properties like topologically protected states or new states of matter (like excitonic insulators) produced by the photo-excitation
process. HHG can potentially shed light on these phenomena by reveali
