Optical Absorption of CuO antiferromagnetic chains at finite temperatures
Eduardo Gagliano, Fabian Lema, Silvia Bacci +2
We use a high-statistic quantum Monte Carlo and Maximum Entropy regularization method to compute the dynamical energy correlation function (DECF) of the one-dimensional (1D) $S=1/2…
Magnetic Raman Scattering of Insulating Cuprates
J. M. Eroles, C. D. Batista, S. B. Bacci +1
We study the and Raman profiles of MCu (with M= La, Pr, Nd, Sm, Gd), BiSrCaYCuO%, YBaCuO$_{6.2}…
Superconductivity with s and p-symmetries in an extended Hubbard model with correlated hopping
A. A. Aligia, E. Gagliano, Liliana Arrachea +1
We consider a generalized Hubbard model with on-site and nearest-neighbour repulsions U and V respectively, and nearest-neighbour hopping for spin up (down) which depends on the to…
"Superconductor"-insulator transitions in a Hubbard chain with nearest- neighbor and bond-charge interactions
A. A. Aligia, E. R. Gagliano
We consider a half-filled generalized Hubbard chain with electron-hole symmetric correlated hopping and on-site and nearest-neighbor repulsions U and V respectively. In addition to…
Optical properties of an effective one-band Hubbard model for the cuprates
M. E. Simon, A. A. Aligia, E. R. Gagliano
We study the Cu and O spectral density of states and the optical conductivity of CuO_2 planes using an effective generalized one-band Hubbard model derived from the extended three-…
Anomalous flux quantization in a Hubbard ring with correlated hopping
Liliana Arrachea, A. A. Aligia, E. Gagliano
We solve exactly a generalized Hubbard ring with twisted boundary conditions. The magnitude of the nearest-neighbor hopping depends on the occupations of the sites involved and the…
