Ground and Metastable States in -Ce from Correlated Band Theory
A. B. Shick, W. E. Pickett, A. I. Liechtenstein
Multiple energy minima of the LDA+U energy functional are obtained for -Ce when it is implemented in a full potential, rotationally invariant scheme including spin-orbit couplin…
Implementation of the LDA+U method using the full potential linearized augmented plane wave basis
A. B. Shick, A. I. Liechtenstein, W. E. Pickett
We provide a straightforward and efficient procedure to combine LDA+U total energy functional with the full potential linearized augmented plane wave method. A detailed derivation…
Where are holes in Y_{1-x}Pr_xBa2Cu3O7 ?
I. I. Mazin, A. I. Liechtenstein
Recent experiments by Mertz et al (Phys. Rev. B55, 9160, 1997) demonstrated that the loss of superconductivity upon Pr doping is associated with the change of the character of the…
Out-of-plane instability and electron-phonon contribution to s- and d-wave pairing in high-temperature superconductors; LDA linear-response calculation for doped CaCuO2 and a generic tight-binding model
O. K. Andersen, S. Y. Savrasov, O. Jepsen +1
The equilibrium structure, energy bands, phonon dispersions, and s- and d-channel electron-phonon interactions (EPIs) are calculated for the infinite-layer superconductor CaCuO2 do…
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…
