Spectral Anomaly and High Temperature Superconductors
Spectral anomaly for interacting Fermions is characterized by the spectral function A([k − kF ], ω) satisfying the scaling relation A(Λy1 [k − kF ],Λy2ω) = ΛyAA([k − kF ], ω), where y1, y2, and yA are the exponents defining the universality class. For a Fermi liquid y1 = 1, y2 = 1, yA = −1; all other values of the exponents are termed anomalous. In this paper, an example for which y1 = 1, y2 = ...
متن کاملPairing Symmetry of the High Temperature Superconductors
A review of relevant experiments that favour an unconventional pairing symmetry in high temperature cuprates is made. Results of magnitude sensitive techniques are discussed and then tests which probe directly the phase of the order parameter are presented in more detail. Josephson eeect and its relevance to this problem is described. Consensus resulting from compelling arguments for a d x 2 ?y...

متن کاملVortex charges in high-temperature superconductors.
Based on a model Hamiltonian with competing antiferromagnetic (AF) and d-wave superconductivity interactions, the vortex charge is investigated by solving the Bogoliubov-de Gennes equations. We found that the vortex charge is negative when a sufficient strength of AF order is induced inside the vortex core; otherwise, it is positive. By tuning the on-site Coulomb repulsion U or the doping param...
متن کاملMICROMAGNETISM IN URu2Si2 AND HIGH TEMPERATURE SUPERCONDUCTORS
It has been proposed, that unconventional density waves (UDW) are possible candidates for systems with hidden order parameter. Unlike in conventional density waves, no periodic modulation of either the charge-, or the spin-density is present in UDW, in spite of a clear thermodynamic signal. Although the unconventional spin density wave (USDW) has been suggested for the ”antiferromagnetic” phase...
