  author={Bernhard Keimer and Steven A. Kivelson and Michael R. Norman and Satoshi Uchida and Jan Zaanen},
The discovery of high-temperature superconductivity in the copper oxides in 1986 triggered a huge amount of innovative scientific inquiry. In the almost three decades since, much has been learned about the novel forms of quantum matter that are exhibited in these strongly correlated electron systems. A qualitative understanding of the nature of the superconducting state itself has been achieved. However, unresolved issues include the astonishing complexity of the phase diagram, the… 

Introduction to Unconventional Superconductivity and Density Waves in Cuprates

Superconductors, known for their ability to conduct electricity without resistance, are fairly common in nature. This is a result of the fact that, despite the strong interactions between their

Superconductivity in infinite-layer nickelates

The recent discovery of the superconductivity in the doped infinite layer nickelates RNiO2 (R = La, Pr, Nd) is of great interest since the nickelates are isostructural to doped (Ca, Sr)CuO2 having

Condensed-matter physics: Superconducting electrons go missing

A comprehensive study of the key physical properties of the overdoped copper oxide superconductor La2−xSrxCuO4 finds that the scaling law for the critical superconducting temperature and zero-temperature phase stiffness does not conform to standard BCS physics.

Emergent high-temperature superconductivity at interfaces

Low-dimensional superconductors have been at the forefront of physics research due to their rich physical properties such as high-temperature (Tc) superconductivity. In this article, we review the

Signatures of a strange metal in a bosonic system

Fermi liquid theory forms the basis for our understanding of the majority of metals: their resistivity arises from the scattering of well defined quasiparticles at a rate where, in the

Superconductivity in infinite layer nickelates

The discovery of an infinite layer nickelate superconductor in 2019 provided a perfect ending to the long race of searching nearly 30 years for a cuprate analog and at the same time marks a new era

Quantum phase transition from superconducting to insulating-like state in a pressurized cuprate superconductor

Copper oxide superconductors continue to fascinate the communities of condensed matter physics and material sciences because they host the highest ambient-pressure superconducting transition

Scaling of the strange-metal scattering in unconventional superconductors.

Marked evolution of properties with minute changes in the doping level is a hallmark of the complex chemistry that governs copper oxide superconductivity as manifested in the celebrated

Mechanism of High-Temperature Superconductivity in Correlated-Electron Systems

It is very important to elucidate the mechanism of superconductivity for achieving room temperature superconductivity. In the first half of this paper, we give a brief review on mechanisms of



Phenomenology of the normal state of Cu-O high-temperature superconductors.

The universal anomalies in the normal state of Cu-O high-temperature superconductors follow from a single hypothesis: There exist charge- and spin-density excitations with the absorptive part of the polarizability at low frequencies proportional to T, where T is the temperature, and constant otherwise.

Quantum oscillations in an overdoped high-Tc superconductor

The nature of the metallic phase in the high-transition-temperature (high-Tc) copper oxide superconductors, and its evolution with carrier concentration, has been a long-standing mystery. A central

Quantum oscillations and the Fermi surface in an underdoped high-Tc superconductor

The observation of quantum oscillations in the electrical resistance of the oxygen-ordered copper oxide YBa2Cu3O6.5 establishes the existence of a well-defined Fermi surface in the ground state of underdoped copper oxides, once superconductivity is suppressed by a magnetic field.

High-temperature interface superconductivity between metallic and insulating copper oxides

The realization of high-transition-temperature (high-Tc) superconductivity confined to nanometre-sized interfaces has been a long-standing goal because of potential applications and the opportunity

Electronic phase diagram of high-temperature copper oxide superconductors

The evolution of the normal state electronic excitations with temperature and carrier concentration in Bi2Sr2CaCu2O8+δ using angle-resolved photoemission is examined to find that T∗ and Tcoh are strongly doping dependent and cross each other near optimal doping.

Intense paramagnon excitations in a large family of high-temperature superconductors

In the copper oxide superconductors, spin fluctuations might be involved in the electronic pairing mechanism. The case for such magnetically mediated superconductivity is now strengthened by the

Superconductivity at 39 K in Magnesium Diboride.

In the light of the tremendous progress that has been made in raising the transition temperature of the copper oxide superconductors (for a review, see ref. 1), it is natural to wonder how high the

Electronic Liquid Crystal State in the High-Temperature Superconductor YBa2Cu3O6.45

The spontaneous onset of a one-dimensional, incommensurate modulation of the spin system in the high-transition-temperature superconductor YBa2Cu3O6 suggests that soft spin fluctuations are a microscopic route toward electronic liquid crystals and that nematic order can coexist with high-tem temperature superconductivity in underdoped cuprates.

We use a variational approach to gain insight into the strongly correlated $d$-wave superconducting state of the high ${T}_{c}$ cuprates at $T=0$. We show that strong correlations lead to

Normal-state nodal electronic structure in underdoped high-Tc copper oxides

An outstanding problem in the field of high-transition-temperature (high-Tc) superconductivity is the identification of the normal state out of which superconductivity emerges in the mysterious
