The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

This article reviews the physics of high-temperature superconductors from the point of view
of the doping of a Mott insulator. The basic electronic structure of cuprates is reviewed …

The last decade witnessed significant progress in angle-resolved photoemission
spectroscopy (ARPES) and its applications. Today, ARPES experiments with 2-meV energy …

The spectral energy gap is an important signature that defines states of quantum matter:
insulators, density waves and superconductors have very different gap structures. The …

This review presents recent developments in the understanding of how impurities influence
the electronic states in the bulk properties of superconductors. The focus is on …

Coupling between electrons and phonons (lattice vibrations) drives the formation of the
electron pairs responsible for conventional superconductivity. The lack of direct evidence for …

We present the full analysis of the normal state properties of the spin-fermion model near the
antiferromagnetic instability in two dimensions. The model describes low-energy fermions …

One of the first theoretical proposals for understanding high-temperature superconductivity
in the cuprates was Anderson's RVB theory using a Gutzwiller projected BCS wavefunction …

Although nineteen years have passed since the discovery of high temperature cuprate
superconductivity, there is still no consensus on its physical origin. This is in large part …

One of the keys to the high-temperature superconductivity puzzle is the identification of the
energy scales associated with the emergence of a coherent condensate of superconducting …
