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 …

'Conventional'superconductivity, as used in this review, refers to electron–phonon-coupled
superconducting electron pairs described by BCS theory. Unconventional superconductivity …

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

Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

Inelastic light scattering is an intensively used tool in the study of electronic properties of
solids. Triggered by the discovery of high-temperature superconductivity in the cuprates and …

This topical review summarizes various features of magnetic penetration depth in
unconventional superconductors. Precise measurements of the penetration depth as a …

We present an angle-resolved photoemission do** dependence study of the n-type
cuprate superconductor Nd 2− x Ce x CuO 4±δ, from the half-filled Mott insulator to the T c …

We review the field of high temperature cuprate superconductors, with emphasis on the
nature of their electronic properties. After a general overview of experiment and theory, we …

The Hall coefficient RH of the cuprate superconductor YBa 2 Cu 3 O y was measured in
magnetic fields up to 60 T for a hole concentration p from 0.078 to 0.152 in the underdoped …

Cluster perturbation theory is a technique for calculating the spectral weight of Hubbard
models of strongly correlated electrons, which combines exact diagonalizations on small …
