Theory of superconductivity in doped cuprates

Within the t-t-J model, the physical properties of doped cuprates in the superconducting-state are discussed based on the kinetic energy driven superconducting mechanism. We show that the superconducting-state in cuprate superconductors is controlled by both superconducting gap parameter and single particle coherence, and then quantitatively reproduce some main features found in the experiments...

Doping-dependent charge order correlations in electron-doped cuprates

Understanding the interplay between charge order (CO) and other phenomena (for example, pseudogap, antiferromagnetism, and superconductivity) is one of the central questions in the cuprate high-temperature superconductors. The discovery that similar forms of CO exist in both hole- and electron-doped cuprates opened a path to determine what subset of the CO phenomenology is universal to all the ...

Competition between antiferromagnetism and superconductivity in the electron-doped cuprates triggered by oxygen reduction.

We have performed a systematic angle-resolved photoemission study of as-grown and oxygen-reduced Pr(2-x)CexCuO4 and Pr(1-x)LaCexCuO4 electron-doped cuprates. In contrast with the common belief, neither the band filling nor the band parameters are significantly affected by the oxygen reduction process. Instead, we show that the main electronic role of the reduction process is to remove an anisot...
