Similarities between the $t - J$ and Hubbard models in weakly correlated regimes

Marie-Bernadette Lepetit, Marie-Liesse Doublet, Philippe Maurel

We present a comparative study of the Hubbard and $t - J$ models far away from half-filling. We show that, at such fillings the $t - J$ Hamiltonian can be seen as an effective model of…

Fractionnally charged excitations in the charge density wave state of a quarter-filled t-J chain with quantum phonons

Philippe Maurel, Marie-Bernadette Lepetit, Didier Poilblanc

Elementary excitations of the 4k $_{F}$ charge density wave state of a quarter-filled strongly correlated electronic one-dimensional chain are investigated in the presence of dispersi…
