Logarithmic divergent specific heat from high-temperature series expansions: application to the two-dimensional XXZ Heisenberg model
M. G. Gonzalez, B. Bernu, L. Pierre +1
We present an interpolation method for the specific heat , when there is a phase transition with a logarithmic singularity in at a critical temperature . The m…
Interplay between spatial anisotropy and further exchange interactions in the triangular Heisenberg model
M. G. Gonzalez, E. A. Ghioldi, C. J. Gazza +2
We investigate the interplay between spatial anisotropy and further exchange interactions in the spin- Heisenberg antiferromagnetic model on a triangular lattice. We u…
Magnetic phase diagram of the infinite-U Hubbard model with nearest- and next nearest-neighbor hoppings
G. G. Blesio, M. G. Gonzalez, F. T. Lisandrini
We study the infinite-U Hubbard model on ladders of 2, 4 and 6 legs with nearest (t) and next-nearest (t') neighbor hoppings by means of the density-matrix renormalization group al…
Correlated partial disorder in a weakly frustrated quantum antiferromagnet
M. G. Gonzalez, F. T. Lisandrini, G. G. Blesio +3
Partial disorder --the microscopic coexistence of long-range magnetic order and disorder-- is a rare phenomenon, that has been experimental and theoretically reported in some Ising…
Dynamical structure factor of the triangular antiferromagnet: the Schwinger boson theory beyond the mean field approach
E. A. Ghioldi, M. G. Gonzalez, Shang-Shun Zhang +4
We compute the zero temperature dynamical structure factor of the triangular lattice Heisenberg model (TLHM) using a Schwinger boson approach that includes the Gauss…
One dimensionalization in the spin-1 Heisenberg model on the anisotropic triangular lattice
M. G. Gonzalez, E. A. Ghioldi, C. J. Gazza +2
We investigate the effect of dimensional crossover in the ground state of the antiferromagnetic spin- Heisenberg model on the anisotropic triangular lattice that interpolates be…
