Zeeman dependence of the quasiparticle scattering rate and ARPES in copper oxides and related materials
George Kastrinakis
Within a strongly interacting Fermi liquid framework, we calculate the effects of the Zeeman energy for a finite magnetic field, in a metallic system with a van Hove peak in…
An effective 1-band model for the cuprate superconductors
George Kastrinakis
Starting from the copper-oxygen Hamiltonian of the CuO2 planes, we derive analytically an extended 1-band Hubbard Hamiltonian for the electrons on copper sites, through a canonical…
Quasiparticle scattering rate in overdoped superconducting cuprates
George Kastrinakis
We calculate the quasiparticle scattering rate in the superconducting state of the overdoped cuprates, in the context of the Eliashberg formalism for a Fermi liquid with strong van…
Dominant mode in the cuprates: electronic vs. phononic scenario
George Kastrinakis
We make the case for an electronic origin of the strong mode, recently seen in ARPES experiments, and, in this regard, further discuss the physics of the spin resonance peak.
Cuprates: experiment vs. quasiparticle theory
George Kastrinakis
Comment on the view of P.W. Anderson on the cuprates, as expressed in the Feb. '00 issue of Physics Today.
