Classical heisenberg model
Webthe current understanding is, for O(3) classical Heisenberg model in 2d, there is no finite T transition as interaction of Goldstone particles in two dimensions lead to the infrared … Web2 days ago · Download PDF Abstract: We study the transport and equilibration properties of a classical Heisenberg chain, whose couplings are random variables drawn from a one-parameter family of power-law distributions. The absence of a scale in the couplings makes the system deviate substantially from the usual paradigm of diffusive spin …
