The competition between spin glass (SG) and antiferromagnetic order (AF) is analyzed in two-sublattice fermionic Ising models in the presence of a transverse G and a parallel H magnetic fields. The exchange interaction follows a Gaussian probability distribution with mean Γ4J 0 =N and standard devia
We illustrate, in the limit of small values of the parameter b, a method to analyze the stochastic equations governing the time evolution of a two-junction quantum interferometer in the presence of noise. The analysis takes into account the different characteristic times of the two processes involve
