Multicritical Behavior in a Random-Field Ising Model under a Continuous-Field Probability Distribution
Octavio R. Salmon, Nuno Crokidakis, Fernando D. Nobre
A random-field Ising model that is capable of exhibiting a rich variety of multicritical phenomena, as well as a smearing of such behavior, is investigated. The model consists of a…
q-Gaussians in the porous-medium equation: stability and time evolution
Veit Schwämmle, Fernando D. Nobre, Constantino Tsallis
The stability of -Gaussian distributions as particular solutions of the linear diffusion equation and its generalized nonlinear form, $\pderiv{P(x,t)}{t} = D \pderiv{^2 [P(x,t)]…
Ising spin glass under continuous-distribution random magnetic fields: Tricritical points and instability lines
N. Crokidakis, F. D. Nobre
The effects of random magnetic fields are considered in an Ising spin-glass model defined in the limit of infinite-range interactions. The probability distribution for the random m…
