Crossover in the Ordered Phase in the Non-Mermin-Wagner-Hohenberg Regime of Spin Models with Long-Range Coupling

Jiewei Ding, Jiahao Su, Ho-Kin Tang +1

Continuous spin models with long-range interactions of the form $r^{-\sigma }$, where $r$ is the distance between two spins and $\sigma$ controls the decay of the interaction, exhibit enhance…
