Chiral d-wave superconductor with nonzero center-of-mass pair momentum
V. I. Belyavsky, V. V. Kapaev, Yu. V. Kopaev
Hypothetical topologically nontrivial superconducting state of two-dimensional electron system is discussed in connection with the problem of pairing with large center-of-mass pair…
Haldane state with toroidal magnetic order
V. I. Belyavsky, Yu. V. Kopaev
We show that a simplified two-band model describing toroidal magnetic order in two-dimensional crystal is entirely equivalent to the well-known Haldane model of a honeycomb lattice…
Checkerboard superconducting order and antinodal Bogoliubov quasiparticle interference
V. I. Belyavsky, V. V. Kapaev, Yu. V. Kopaev
Numerical study of momentum-dependent gap function is presented to make clear the origin of superconductivity in copper oxides. We claim that antinodal region with pronounced nesti…
Biordered superconductivity and strong pseudogap state
V. I. Belyavsky, Yu. V. Kopaev
Interrelation between the two-particle and mean-field problems is used to describe the strong pseudogap and superconducting states in cuprates. We present strong pseudogap state as…
Superconductivity in homologous cuprate series: deep oscillations of pairing Coulomb potential
V. I. Belyavsky, Yu. V. Kopaev
Kinematic constraint arising in the case of superconducting pairing with large momentum results in a cutoff of the screened Coulomb potential excluding large momentum transfers. Th…
Superconductivity from repulsion: Ginzburg-Landau phenomenology of cuprates
V. I. Belyavsky, Yu. V. Kopaev
We develop Ginzburg-Landau approach to the problem of superconducting pairing with large momentum under screened Coulomb repulsion (eta_K-pairing). Two-component order parameter ar…
