Superconducting pairing of spin polarons in the t-J model
N. M. Plakida, V. S. Oudovenko, P. Horsch +1
The pairing of quasiparticles in a CuO plane is studied within a spin polaron formulation of the -- model. Our numerical solution of the Eliashberg equations unamb…
LDA energy bands, low-energy Hamiltonians, t', t'', t_{perp}(k), and J_{perp}
O. K. Andersen, A. I. Liechtenstein, O. Jepsen +1
We describe the LDA bandstructure of YBa_2Cu_3O_7 in the 2 eV range from the Fermi energy using orbital projections and compare with YBa_2Cu_4O_8. Then, the high-energy and chain-r…
Antiferromagnetic Interactions and the Superconducting Gap Function
R. J. Radtke, A. I. Liechtenstein, V. M. Yakovenko +1
Spin-fluctuation-mediated superconductivity is conventionally associated with d_{x^2-y^2} pairing. We show that a generalized model of antiferromagnetic spin fluctuations in three…
