In this paper, the authors review the results of a wide variety of experiments on materials such as weakly coupled antiferromagnetic insulators with very large Heisenberg exchange energies, which become high-temperature superconductors when charge carriers are added to the layers.Abstract:
The authors review the results of a wide variety of experiments on materials such as ${\mathrm{La}}_{2}{\mathrm{CuO}}_{4}$ and ${\mathrm{Nd}}_{2}{\mathrm{CuO}}_{4}$ that contain weakly coupled ${\mathrm{CuO}}_{2}$ layers. These materials are antiferromagnetic insulators with very large Heisenberg exchange energies, which become high-temperature superconductors when charge carriers are added to the ${\mathrm{CuO}}_{2}$ layers. The growth of large single crystals has made it possible to carry out neutron scattering, as well as anisotropic optical, transport, and magnetization measurements. The properties of the undoped ${\mathrm{CuO}}_{2}$ layer are reviewed, and the evolution of magnetic, optical, and transport properties with the addition of charge carriers is discussed. The emphasis is on the pure and lightly doped materials, although the magnetism in the superconductors is discussed.read more

Doping a Mott insulator: Physics of high-temperature superconductivity
TL;DR: In this paper, a review of the physics of high-temperature superconductors from the point of view of the doping of a Mott insulator is presented, with the goal of putting the resonating valence bond idea on a more formal footing.

Doping a Mott Insulator: Physics of High Temperature Superconductivity
TL;DR: In this article, Anderson's idea of the resonating valence bond (RVB) was introduced to describe the spin liquid phase of the undoped Mott insulator, and the slave-boson is introduced to enforce the constraint of no double occupation.

How to detect fluctuating stripes in the high-temperature superconductors

TL;DR: In this paper, the authors compare and contrast the advantages of two limiting perspectives on the high-temperature superconductor: weak coupling, in which correlation effects are treated as a perturbation on an underlying metallic (although renormalized) Fermi-liquid state, and strong coupling, where the magnetism is associated with well defined localized spins, and stripes are viewed as a form of micro phase separation.
