Nonlinear susceptibility of a quantum spin glass under uniform transverse and random longitudinal magnetic fields
S. G. Magalhaes, C. V. Morais, F. M. Zimmer +2
The interplay between quantum fluctuations and disorder is investigated in a spin-glass model, in the presence of a uniform transverse field , and a longitudinal random field fo…
The spectral gap and the dynamical critical exponent of an exact solvable probabilistic cellular automaton
M. J. Lazo, A. A. Ferreira, F. C. Alcaraz
We obtained the exact solution of a probabilistic cellular automaton related to the diagonal-to-diagonal transfer matrix of the six-vertex model on a square lattice. The model desc…
Spin-1 Hopfield model under a random field
C. V. Morais, M. J. Lazo, F. M. Zimmer +2
The goal of the present work is to investigate the role of trivial disorder and nontrivial disorder in the three-state Hopfield model under a Gaussian random field. In order to con…
Inverse freezing in the Ghatak-Sherrington model with a random field
C. V. Morais, M. J. Lazo, F. M. Zimmer +1
The present work studies the Ghatak-Sherrington (GS) model in the presence of a magnetic random field (RF). Previous results obtained from GS model without RF suggest that disorder…
The Exact Solution of the Asymmetric Exclusion Problem With Particles of Arbitrary Size: Matrix Product Ansatz
Francisco C Alcaraz, M J Lazo
The exact solution of the asymmetric exclusion problem and several of its generalizations is obtained by a matrix product {\it ansatz}. Due to the similarity of the master equation…
