متن کاملBogoliubov angle in electron-doped cuprate superconductors
Within the framework of the kinetic energy driven superconducting mechanism, the momentum dependence of the Bogoliubov angle in the electron-doped cuprate superconductors is studied. By calculation of the ratio of the low energy quasiparticle spectra at positive and negative energies, it is shown that the Bogoliubov angle increases monotonically across the Fermi crossing point, suggesting a con...
متن کاملStripe order and quasiparticle Nernst effect in cuprate superconductors
After a brief review of current ideas on stripe order in cuprate high-temperature superconductors, we discuss the quasiparticle Nernst effect in cuprates, with focus on its evolution in non-superconducting stripe and related nematic states. In general, we find the Nernst signal to be strongly enhanced by nearby van-Hove singularities and Lifshitz transitions in the band structure, implying that...

متن کاملNernst effect in the electron-doped cuprates
We calculate the normal state Nernst signal in the cuprates resulting from a reconstruction of the Fermi surface due to spin density wave order. An order parameter consistent with the reconstruction of the Fermi surface detected in electron-doped materials is shown to sharply enhance the Nernst signal close to optimal doping. Within a semiclassical treatment, the obtained magnitude and position...
