![]() ![]() We further support this idea by numerical determination of νeff in suitably chosen models. ![]() Can you explain them all in terms of the lower level Weak emergence is where. Away from criticality we describe a mechanism that could account for the emergence of an effective critical exponent ν_eff, which is necessarily dependent on the parameters of the model. Emergence is when you put simple things together and new behaviours emerge. In the future, our numerical findings can be checked with analytical results from the conformal field theory. At criticality, we show that the finite-size scaling of the disorder averaged longitudinal Landauer conductance is consistent with its recently predicted fixed-point value and a third-order expansion of RG beta functions. ![]() In this work, we provide numerical evidence for such a scenario by using extensive simulations of various network models of the IQHT at unprecedented length scales. A stage in recovery from general anesthesia that includes a return to spontaneous breathing, voluntary swallowing, and normal consciousness. Zirnbauer has conjectured a conformal field theory for the transition, in which linear terms in the beta-functions vanish, leading to a very slow flow in the fixed point’s vicinity which we term marginal scaling. Despite all efforts, it is notoriously difficult to pin down the precise values of critical exponents, which seem to vary with model details and thus challenge the principle of universality. Since the 1980s, the scaling behavior near the IQHT has been vigorously studied in experiments and numerical simulations.
