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

Understanding the mechanism responsible for superconductivity in the high-temperature
cuprates has been one of the major goals of condensed-matter physicists since the …

Although copper oxide high-temperature superconductors constitute a complex and diverse
material family, they all share a layered lattice structure. This curious fact prompts the …

Tunneling spectroscopy has played a central role in the experimental verification of the
microscopic theory of superconductivity in classical superconductors. Initial attempts to apply …

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 …

We present an experiment designed to determine directly the symmetry of the pairing state
in the cuprate superconductors. From the magnetic flux modulation of YBCO-Pb dc SQUIDs …

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

It is shown that a sizable areal density of midgap states exists on a {110} surface of adxa 2-
xb 2-wave superconductor, which can either have vacuum or an insulator at the surface, or …

The quest for higher data density in information storage is motivating investigations into
approaches for manipulating magnetization by means other than magnetic fields. This is …

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 …
