The nature of resistive transition of high-quality crystalline thin films of YBa2Cu3O7-δhas been studied under magnetic fields(H) applied along the c direction over a wide range of doped holes, p, in the Cu O2 plan...
This paper gives methods to calculate the pairing temperature T*, at which a pseudogap is opened, and the superconducting temperature Tc, at which superconductivity appears, in the high-Te cuprates, and demonstrates ...

The last 15 years have witnessed important progresses in our understanding of the mechanism of superconductivity in the high-Tc cuprates.There is now strong evidence that the strange metal behavior is induced by the q...

Superconducting metal dichalcogenides(MDCs)present several similarities to the other layered SI1-perconductors like cuprates.The superconductivity in atomically thin MDCs has been demonstrated by recent experiments,ho...
A mean-field spin-density wave (SDW) analysis of pseudogap in the underdoped cuprates is proposed on the dependence of the energy gap which mimics the pseudogap near (π, 0) point at least. It implies that the pseudog...

The pseudogap state is one of the most enigmatic characteristics in the anomalous normal state properties of the high temperature cuprate superconductors. A central issue is to reveal whether there is a symmetry break...

The one-electron spectral function of a frustrated Hubbard chain is computed by making use of the cluster perturbation theory. The spectral weight we found turns out to be strongly dependent on the frustrating next-ne...
Looking back on the experiments about the normal state of the high temperature superconductor (NTS), the authors point out nine important experimental results. On the basis of these results, the authors have argued th...
This paper deduces that the particular electronic structure of cuprate superconductors confines Cooper pairs to be first formed in the antinodal region which is far from the Fermi surface, and these pairs are incohere...
