(Left) Expectation value 〈σ〉 as a function of temperature, red curve: ΔH = 400 K, ΔS = 2, no disorder, violet curve: ΔH = 300 K, ΔS = 2, no disorder, black curve: ΔH = 400 K, ΔS = 2, the disorder above Tst = 300 K is modelled with α = 0.1, K = 4 K; J = 100 K for all curves. (Right) a measure of radiation-induced disorder as a function of temperature. |
