Why high-pressure matters

• Beatrice D'Alò

Over the past century, high-pressure experiments led to intriguing physics discoveries, revealing new phases of materials and enabling the synthesis of novel compounds. In this talk, I will briefly discuss the significance of high-pressure experiments and introduce the most used and iconic device for generating high static pressures: the diamond anvil cell (DAC). The often-overlooked experimental aspects of working with DACs will be discussed, and a high-pressure experiment on 2D materials will be presented.

How 2D-isentangle nonlinear response of quantum materials

• Jacopo Fiore

In this talk, I will introduce the key tools required to understand the nonlinear interaction between light and quantum materials through many-body perturbation theory. We will explore how various experimental techniques can probe the information encoded in nonlinear optical response functions, which can be computed using low-energy models that describe symmetry-broken phases of condensed matter systems. Special emphasis will be placed on the cutting-edge application of multidimensional THz spectroscopy in superconductors.
