Competition between superconductivity and the pseudogap phase in the t-J model
R. Zeyher, A. Greco
The t-J model in the large N limit (N denotes the number of spin components) yields a pseudogap phase in the underdoped region which is related to a d-wave charge density wave (d-C…

Influence of collective effects and the d-CDW on electronic Raman scattering in high-T superconductors
R. Zeyher, A. Greco
Electronic Raman scattering in high-T superconductors is studied within the t-J model. It is shown that the A and B spectra are dominated by amplitude fluctuation…

Large-N expansion based on the Hubbard-operator path integral representation and its application to the model
Adriana Foussats, Andres Greco
In the present work we have developed a large-N expansion for the model based on the path integral formulation for Hubbard-operators. Our large-N expansion formulation contai…
