The origin of the exceptionally strong superconductivity of cuprates remains a subject of
debate after more than two decades of investigation. Here we follow a new lead: The onset …

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

Some of the highest-transition-temperature superconductors across various materials
classes exhibit linear-in-temperature 'strange metal'or 'Planckian'electrical resistivities in …

Strange metal behavior is traditionally associated with an underlying putative quantum
critical point at zero temperature. However, in many correlated metals, eg, high-T c cuprate …

Over the past 35 years, research on unconventional superconductivity in heavy-fermion
systems has evolved from the surprising observations of unprecedented superconducting …

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 …

Electronic nematic materials are characterized by a lowered symmetry of the electronic
system compared to the underlying lattice, in analogy to the directional alignment without …

A continuous phase transition driven to zero temperature by a non-thermal parameter, such
as pressure, terminates in a quantum critical point (QCP). At present, two main theoretical …

We study a controlled large-N theory of electrons coupled to dynamical two-level systems
(TLSs) via spatially random interactions. Such a physical situation arises when electrons …

Ce115 and related Ce compounds are particularly suited to detailed studies of the interplay
of antiferromagnetic order, unconventional superconductivity and quantum criticality due to …
