Impact of the spin-wave interaction in ferromagnets

We analyze the low-temperature properties of ferromagnets in one, two and three space dimensions up to three-loop order in the effective expansion, i.e., beyond the accuracy of any previous results obtained with conventional condensed matter methods. Remarkably, in the nonrelativistic domain, the effective method perfectly works in one spatial dimension.
