WebWe introduce a new nonconservative self-organized critical model. This model is equivalent to a quasistatic two-dimensional version of the Burridge-Knopoff spring-block model of earthquakes. Our model displays a robust power-law behavior. The exponent is not universal; rather it depends on the level of conservation. A dynamical phase transition … WebSep 26, 2024 · Numerical simulations of the continuous version of the BCS model have indicated the existence of a universal continuous phase transition at a critical value p = p c with mean field exponents ν = 2.00 (1) for the correlation length, β = 0.50 (1) for the order parameter and γ = 1.00 (1) for the order parameter fluctuation (susceptibility).
