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...

Electrolytes can be used to very effectively transfer the electrostatic potential from a metal electrode (gate) to the surface of a semiconductor, to realize ionically gated devices. Even though the technique is by now long established, its application to 2D materials...

The so-called strange metals are characterized by various anomalous properties, the most famous of which being a resistivity that remains linear down to the lowest temperatures. Such behavior is observed in several systems, starting historically from the cuprates and...

Ferroelectrics are materials exhibiting a remanent polarisation that can be switched by applying an electric field. These materials can consist of regions where the polarisation points in different directions, and each region with a uniform polarisation is called a...
