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...

In 2020 a publication in Nature announced the discovery of room-temperature superconductivity in a carbonaceous sulfur hydride. On 15 February 2022 the following statement was issued “The editors of Nature have been alerted to concerns regarding the manner in which...

The electronic band structure of atomically thin semiconductors can be tuned by applying a perpendicular electric field. The principle was demonstrated experimentally shortly after discovering graphene by opening a finite band gap (~100 meV) in graphene bilayers...

I will present recent results on the exciton-polaron spectroscopy for the investigation of strongly correlated electronic states in homobilayers heterostructures. I will also discuss insights from the theory on the origin of incompressible electronic states in these...

Recent experimental observations have shown that twisted transition metal dichalcogenides (TMDs) may host correlated phases which develop in presence of a Moiré superlattice [1,2]. Coupling to this long-wavelength periodic potential results in the formation of weakly...
