It has long been thought that strongly correlated systems are adiabatically connected to their
non-interacting counterpart. Recent developments have highlighted the fallacy of this …

Quantum phase transitions arise in many-body systems because of competing interactions
that promote rivaling ground states. Recent years have seen the identification of continuous …

Quantum-mechanical phenomena underpin the behaviour of quantum materials at the
microscopic level. The description of several essential properties of these materials …

Twisted van der Waals materials have been shown to host a variety of tunable electronic
structures. Here we put forward twisted trilayer graphene (TTG) as a platform to emulate …

Strongly correlated systems present fundamental challenges, especially in materials in
which electronic correlations cause a strong increase of the effective mass of the charge …

Strange-metal phenomena often develop at the border of antiferromagnetic order in strongly
correlated metals. Previous work established that they can originate from the fluctuations …

The observation of a separation between the antiferromagnetic phase boundary and the
small-large Fermi surface transition in recent experiments has led to the proposal that …

How ground states of quantum matter transform between one another reveals deep insights
into the mechanisms stabilizing them. Correspondingly, quantum phase transitions are …

Quantum criticality arises when a macroscopic phase of matter undergoes a continuous
transformation at zero temperature. While the collective fluctuations at quantum-critical …

This article overviews the development of heavy-fermion superconductivity, notably in such
rare-earth-based intermetallic compounds which behave as Kondo-lattice systems. Heavy …
