On the Theory of Magnets with Competing Double Exchange and Superexchange Interactions
D. I. Golosov, M. R. Norman, K. Levin
In the CMR materials, ferromagnetic double exchange (DE) presumably coexists with a direct nearest-neighbour antiferromagnetic interaction. We construct a single-site mean field th…
A Theory of Magnets with Competing Double Exchange and Superexchange Interactions
D. I. Golosov, M. R. Norman, K. Levin
We study the competition between ferromagnetic double exchange (DE) and nearest-neighbour antiferromagnetic exchange in CMR materials. Towards this end, a single site mean field th…
What does d-wave symmetry tell us about the pairing mechanism?
K. Levin, D. Z. Liu, Jiri Maly
In this paper we argue that d-wave symmetry is a general consequence of superconductivity driven by repulsive interactions. Van Hove (or flat band) effects, deriving from the two d…
An Alternative Route to D-wave Superconductivity: the Charge Channel
Dong-Zi Liu, K. Levin
We demonstrate that a superconducting pairing is naturally associated with the screened Coulomb interaction within the plane of high $T_c…
Neutron Scattering and -Wave Symmetry in the Cuprates
Yuyao Zha, K. Levin
In this comment we demonstrate that the general conjectures of Fong on their neutron experiments are realized in concrete calculations of the neutron…
Superconducting Order Parameter in Bi-Layer Cuprates: Occurrence of Phase Shifts in Corner Junctions
D. Z. Liu, K. Levin, J. Maly
We study the order parameter symmetry in bi-layer cuprates such as YBaCuO, where interesting phase shifts have been observed in Josephson junctions. Taking models which represe…
