High-temperature superconductivity

open access: yesNature Reviews Physics, 2021
Despite decades of intense theoretical, experimental and computational effort, a microscopic theory of high-temperature superconductivity is not yet established.

High-temperature superconducting resonators

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1992
Preliminary measurements on high-T(c) superconducting resonators are reported and why they are attractive candidates for incorporation in low-noise oscillators is discussed. Some of the important contributions to oscillator noise are reviewed and how they depend on the resonator parameters is shown. A preliminary YBaCu (3)O(7)/LaAlO(3) resonator with a

High-Temperature Superconductivity [PDF]

open access: yes, 1992
In the spring of 1986, K.A. Muller and J.G. Bednortz [1] revealed that at temperatures higher that 30 K the ceramic compounds of lanthanum, barrium and copper oxides go into a superconducting state. In February, 1987, C.W. Chu et al. [2] synthesized yttrium compounds which go over into a superconducting state at temperatures T c close to 90 K.

Mechanism for high-temperature superconductivity

Physical Review B, 1988
An explanation of the mechanism for high-temperature superconductivity is given, based upon a strong-coupling analysis of the extended Hubbard model previously introduced by one of us. The basic carriers are oxygen-hole quasiparticles in p\ensuremath{\sigma} orbitals, whose spin is strongly correlated with that of adjacent copper holes.

High temperature superconductivity in ceruloplasmin

Physica C: Superconductivity, 1988
Abstract Some experimental evidences of the occurrence of High-Temperature Superconductivity (T c ≅ 135 °K) in thermally stored Ceruloplasmin are reported and compared with the AG theory. Interpretation in terms of the GKG model of “Excitonic Superconductivity” leads to a consistent picture of the phenomenon.

Plasmons and high-temperature superconductivity

Physical Review B, 1989
Long-wavelength charge fluctuation models are constructed for 1:2:3 superconductors. These include planar plasmons (..omega..approx. ..sqrt..q ) plus numerous acoustical plasmons (..omega..approx.q). We show that these modes do not cause pairing of electrons into a superconductor state.
