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...

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...

In oxide heterostructures, different materials are integrated into a single artificial crystal, resulting in a breaking of inversion symmetry across the heterointerfaces. A notable example are interfaces between polar and nonpolar materials, where structural...

Quasicrystals are a fascinating state of matter which is characterized by long-range but nonperiodic order. They display a number of intriguing properties, including unusual localization properties, fractal properties and anomalous critical scalings. Such structures...

One of the major challenges in understanding high-temperature superconductivity in copper oxides, is to disentangle the rich variety of electronic phases that can co-exist, cooperate or compete with d-wave superconductivity. In this context, much theoretical and...

A recent ARPES study on surface doped black phosphorus reported funny non-monotonous k(E) dispersions near the chemical potential [1]. I will discuss this paper and show that dispersive “band-like” features in ARPES do not always imply Bloch states. If time permits, I...
