Cuprates exhibit exceptionally strong superconductivity. To understand why, it is essential to
elucidate the nature of the electronic interactions that cause pairing. Superconductivity …

Superconductivity has been discovered recently in infinite-layer nickel-based 112 thin films
R 1− x A x NiO 2 (R= La, Nd, Pr and A= Sr, Ca). They are isostructural to the infinite-layer …

The occurrence of superconductivity in proximity to various strongly correlated phases of
matter has drawn extensive focus on their normal state properties, to develop an …

NATURE abounds with phase transitions. The boiling and freezing of water are everyday
examples of phase transitions, as are more exotic processes such as superconductivity and …

We present an experimental review of the nature of the pseudogap in the cuprate
superconductors. Evidence from various experimental techniques points to a common …

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 …

The authors review the results of a wide variety of experiments on materials such as La 2
CuO 4 and Nd 2 CuO 4 that contain weakly coupled CuO 2 layers. These materials are …

The high-temperature copper oxide superconductors are of fundamental and enduring
interest. They not only manifest superconducting transition temperatures inconceivable 15 …

Scanning tunneling microscopy is used to image the additional quasi-particle states
generated by quantized vortices in the high critical temperature superconductor …

We propose that the enigmatic pseudogap phase of cuprate superconductors is
characterized by a hidden broken symmetry of dx 2− y 2-type. The transition to this state is …
