Dynamic structure factor of the three-dimensional Ising model with purely relaxational dynamics
Dynamic structure factor of the three-dimensional Ising model with purely relaxational dynamics
We compute the dynamic structure factor for the three-dimensional Ising model with a purely relaxational dynamics (model A). We perform a perturbative calculation in the epsilon expansion, at two loops in the high-temperature phase and at one loop in the temperature magnetic-field plane, and a Monte Carlo simulation in the …
