Superconductivity in the t-J model
N. M. Plakida
A comparison of microscopic theories of superconductivity in the limit of strong electron correlations is presented. We consider results for the two-dimensional t-J model obtained…

Dynamic spin susceptibility in the t-J model
G. Jackeli, N. M. Plakida
Dynamic spin susceptibility is calculated for the t-J model in the paramagnetic phase by applying the memory function method in terms of the Hubbard operators. A self-consistent sy…
