--- res: bibo_abstract: - Selected universal experimental properties of high-temperature superconducting (HTS) cuprates have been singled out in the last decade. One of the pivotal challenges in this field is the designation of a consistent interpretation framework within which we can describe quantitatively the universal features of those systems. Here we analyze in a detailed manner the principal experimental data and compare them quantitatively with the approach based on a single-band model of strongly correlated electrons supplemented with strong antiferromagnetic (super)exchange interaction (the so-called t−J−U model). The model rationale is provided by estimating its microscopic parameters on the basis of the three-band approach for the Cu-O plane. We use our original full Gutzwiller wave-function solution by going beyond the renormalized mean-field theory (RMFT) in a systematic manner. Our approach reproduces very well the observed hole doping (δ) dependence of the kinetic-energy gain in the superconducting phase, one of the principal non-Bardeen-Cooper-Schrieffer features of the cuprates. The calculated Fermi velocity in the nodal direction is practically δ-independent and its universal value agrees very well with that determined experimentally. Also, a weak doping dependence of the Fermi wave vector leads to an almost constant value of the effective mass in a pure superconducting phase which is both observed in experiment and reproduced within our approach. An assessment of the currently used models (t−J, Hubbard) is carried out and the results of the canonical RMFT as a zeroth-order solution are provided for comparison to illustrate the necessity of the introduced higher-order contributions.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Jozef foaf_name: Spałek, Jozef foaf_surname: Spałek - foaf_Person: foaf_givenName: Michał foaf_name: Zegrodnik, Michał foaf_surname: Zegrodnik - foaf_Person: foaf_givenName: Jan foaf_name: Kaczmarczyk, Jan foaf_surname: Kaczmarczyk foaf_workInfoHomepage: http://www.librecat.org/personId=46C405DE-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-1629-3675 bibo_doi: 10.1103/PhysRevB.95.024506 bibo_issue: '2' bibo_volume: 95 dct_date: 2017^xs_gYear dct_identifier: - UT:000391852800006 dct_isPartOf: - http://id.crossref.org/issn/24699950 dct_language: eng dct_publisher: American Physical Society@ dct_title: Universal properties of high temperature superconductors from real space pairing t-J-U model and its quantitative comparison with experiment@ ...
