Microscopic theory of high-temperature superconductivity in strongly correlated electronic systems
N. M. Plakida
A consistent microscopic theory of superconductivity for strongly correlated electronic systems is presented. The Dyson equation for the normal and anomalous Green functions for th…
Magnetic order and spin excitations in layered Heisenberg antiferromagnets with compass-model anisotropies
A. A. Vladimirov, D. Ihle, N. M. Plakida
The spin-wave excitation spectrum, the magnetization, and the Néel temperature for the quasi-two-dimensional spin-1/2 antiferromagnetic Heisenberg model with compass-model interact…
Dynamic spin susceptibility in the t-J model
A. A. Vladimirov, D. Ihle, N. M. Plakida
A relaxation-function theory for the dynamic spin susceptibility in the -- model is presented. By a sum-rule-conserving generalized mean-field approximation (GMFA), the two-s…
Electronic spectrum in cuprates within p-d Hubbard model
N. Plakida, V. Oudovenko
A microscopic theory for electronic spectrum of the CuO2 plane within an effective p-d Hubbard model is proposed. Dyson equation for the one-electron Green function in terms of the…
Antiferromagnetic exchange and spin-fluctuation pairing in cuprate superconductors
N. M. Plakida
A microscopic theory of superconductivity is formulated within an effective - Hubbard model for a CuO2 plane. By applying the Mori-type projection technique, the Dyson equati…
Theory of spin wave excitations of metallic A-type antiferromagnetic manganites
G. Jackeli, N. B. Perkins, N. M. Plakida
The spin dynamic of the metallic A-type antiferromagnetic manganites is studied. An effective nearest-neighbour Heisenberg spin wave dispersion is derived from the double exchange…
