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 …

The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

Heavy-fermion systems represent one of the paradigmatic strongly correlated states of
matter,,,–. They have been used as a platform for investigating exotic behaviour ranging …

The ability to create and manipulate materials in two-dimensional (2D) form has repeatedly
had transformative impact on science and technology. In parallel with the exfoliation and …

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 …

Inversion and time reversal are essential symmetries for the structure of Cooper pairs in
superconductors. The loss of one or both leads to modifications to this structure and can …

Heavy-fermion metals are prototype systems for observing emergent quantum phases
driven by electronic interactions,,,,–. A long-standing aspiration is the dimensional reduction …

Angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy
(STM) have become indispensable tools in the study of correlated quantum materials. Both …

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

When interacting electrons are confined to low dimensions, the electron–electron correlation
effect is enhanced dramatically, which often drives the system into exhibiting behaviours that …
