dc.descriptionThe low-temperature free energy of the spin S quantum Heisenberg ferromagnetic chain in a strong magnetic field is obtained in a two-particle approximation by using exact solution of two-spin-wave problem. The result is beyond the perturbation theory because it incorporates the both bound and scattering state contributions, and the scattering effect is essential as well as the bound state one. In particular the main temperature renormalization of an exchange constant is found to be linear in temperature instead $T^{3/2}$ corresponded to the perturbation theory result.
