چکیده

The charge dynamics in weakly hole doped high temperature superconductors is studied in terms of the accurate numerical solution to a model of a single hole interacting with a quantum lattice in an antiferromagnetic background, and accurate far-infrared ellipsometry measurements. The experimentally observed two electronic bands in the infrared spectrum can be identified in terms of the interplay between the electron correlation and electron-phonon interaction resolving the long standing mystery of the midinfrared band.

Doping-induced change of optical properties in underdoped cuprate superconductors

We report on the ab-plane optical reflectance measurements of single crystals of Y-doped Bi2Sr2CaCu2O8+δ and Pr-doped YBa2Cu3O7−δ over a wide frequency range from 80 to 40 000 cm−1 (10 meV–5 eV) and at temperatures between 20 and 300 K. Y and Pr doping both decrease the hole concentration in the CuO2 planes. This has allowed us to investigate the evolution of ab-plane charge dynamics at doping ...

Unconventional charge order in a co-doped high-Tc superconductor

Charge-stripe order has recently been established as an important aspect of cuprate high-Tc superconductors. However, owing to the complex interplay between competing phases and the influence of disorder, it is unclear how it emerges from the parent high-temperature state. Here we report on the discovery of an unconventional ordered phase between charge-stripe order and (pseudogapped) metal in ...

عدم تقارن الکترون-حفره در کوپراتهای دمای بالا از دید نظری

  Asymmetric features of various physical quantities in the normal and superconducting states between hole- and electron-doped cuprate high-temperature superconductors have been an issue of debate for a long time. Their exploration is very important for the understanding not only of the mechanism of high-Tc superconductivity but also of the nature of doped-Mott insulators. Presented in this rev...

Magnetic resonance at 41meV and charge dynamics in YBa2Cu3O6.95

– We report an Eliashberg analysis of the electron dynamics in YBa2Cu3O6.95. The magnetic resonance at 41 meV couples to charge carriers and defines the characteristic shape in energy of the scattering rate τ−1(T, ω), which allows us to construct the charge-spin spectral density Iχ(ω, T ) at temperature T . The T -dependence of the weight under the resonance peak in Iχ(ω) agrees with experiment...

The Electronic Nature of High Temperature Cuprate Superconductors

We review the field of high temperature cuprate superconductors, with an emphasis on the nature of their electronic properties. After a general overview of experiment and theory, we concentrate on recent results obtained by angle resolved photoemission, inelastic neutron scattering, and optical conductivity, along with various proposed explanations for these results. We conclude by reviewing ef...
