Random Ising model in three dimensions: theory, experiment and simulation – a difficult coexistence
We discuss different approaches to the study of the effect of disorder in the three-dimensional Ising model. From the theoretical point of view, renormalization group calculations provide quite accurate results. Experiments carried out on crystalline mixtures of compounds lead to measurements as...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We discuss different approaches to the study of the effect of disorder in the
three-dimensional Ising model. From the theoretical point of view, renormalization
group calculations provide quite accurate results. Experiments
carried out on crystalline mixtures of compounds lead to measurements as
accurate as three digits on the values of critical exponents. Numerically,
extensive Monte Carlo simulations then pretend to be of comparable accuracy.
Life becomes complicated when details are compared between the
three approaches. |
