Phonon screening in high-temperature superconductors
In good conductors optical phonons are usually screened, and therefore not observed. However, sharp features due to infrared-active modes in the copper-oxygen planes are observed in the optical conductivity of Pr1.85Ce0.15CuO4 and YBa2Cu3O6.95. Oscillator strengths indicate that the screening of these modes is poor or totally absent. These materials are compared with eta-Mo4O11, in which lattic...
متن کاملElectron Phonon Interaction and Strong Correlations in High-Temperature Superconductors: One can not avoid unavoidable
The important role of the electron-phonon interaction (EPI) in explaining the properties of the normal state and pairing mechanism in high-Tc superconductors (HTSC) is discussed. A number of experimental results are analyzed such as: dynamical conductivity, Raman scattering, neutron scattering, ARPES, tunnelling measurements, isotope effect and etc. They give convincing evidence that the EPI is...
متن کاملElectronic dispersion anomalies in iron pnictide superconductors.
Recently, experimental studies of the spin excitation spectrum revealed a strong temperature dependence in the normal state and a resonance feature in the superconducting state of several Fe-based superconductors. Based on these findings, we develop a model of electrons interacting with a temperature dependent magnetic excitation spectrum and apply it to angle resolved photoemission in Ba(1-x)K...
متن کاملPHONON ANOMALIES IN HIGH Tc SUPERCONDUCTORS RELATED TO CHARGE STRIPE ORDER
It is a wideheld belief that the holes doped into the CuO2 planes of the cuprate superconductors tend to segregate into stripes that separate antiphase antiferromagnetic domains. However, solid evidence for such stripe order was obtained so far only for the particular compound La1.48Nd0.4Sr0.12CuO4 (LNSCO) and the closely related one La1.875Ba0.125CuO4. In these two compounds, nuclear and magne...
متن کاملCasimir energies: temperature dependence, dispersion, and anomalies.
Assuming the conventional Casimir setting with two thick parallel perfectly conducting plates of large extent with a homogeneous and isotropic medium between them, we discuss the physical meaning of the electromagnetic field energy W disp when the intervening medium is weakly dispersive but nondissipative. The presence of dispersion means that the energy density contains terms of the form d[ome...
