Dense amorphous materials which exhibits a solid-like behaviour, or ‘structural glasses’, are ubiquitous around us. They span a very wide range of experimental systems in soft matter, condensed matter, or biophysics, such as emulsions, foams, biological tissues,...

I will talk about types and properties of excitons in two-dimensional (2D) van der Waals magnetic insulators and semiconductors, such as CrI3, CrSBr, NiPS3, etc. In these materials excitons couple with the spin-polarized band structure, resulting in various correlated...

The study of strongly interacting electrons in moiré heterostructures of semiconducting transition metal dichalcogenides (sTMDs), such as WSe2 and WS2, has led to the discovery of long sought-after quantum phases and behavior. In addition, strong light-matter...

Many correlated electron systems with diverse magnetic and electronic ground states turn into bad metals at high temperature – that is their resistivity increases with temperature and shows no sign of saturation well beyond the Mott-Ioffe-Regel (MIR) limit. In...

In this talk, I will illustrate through two examples how electronic and structural couplings at oxide interfaces can lead to exciting novel properties and 2D systems [1,2]. A striking example is the interface between LaAlO3 and SrTiO3, two good band insulators, which...

A deeper understanding of the differences between quantum and classical dynamics promises great potential for emerging technologies. Nevertheless, some aspects remain poorly understood, particularly concerning the role of quantum coherence in open quantum systems. It...

Atomically thin semiconductors can be stacked on top of each other with limitless possibilities because there is no need for chemical compatibility or lattice match. Combining these materials leads to the emergence of a broad gamut of new physical phenomena. Here, we...

Simplified as it is, the Hubbard model embodies much of the complexity of the `strong correlation problem’ and has established itself as a paradigmatic model in the field. In this talk, I will argue that several key aspects of its physics in two dimensions can now be...

UTe2 is a recently discovered heavy fermion superconductor. In this Flat Club, I will highlight some of the remarkable properties of this material, with a focus on scanning tunneling microscopy experiments. Differential conductance measurements at step edges have...

EuCd2As2 has emerged as a topological material where magnetism may produce strong effects. This compound has been understood as a candidate Weyl semimetal, based mostly on transport and photoemission measurements. I will present our recent results on samples in which...
