Seminar on "Spin-wave theory for quantum magnets" by M.E.Zhitomirsky (Grenoble)
November 6: Seminar on "Spin-wave theory for quantum magnets" by M.E.Zhitomirsky (CEA-INAC/UJF, Grenoble)
This lecture reviews the basic principles and results of the Spin-Wave theory.
In addition, multiparticle effects will be considered, incudling spontaneous decay of magnons in non-cllinear magnets and magnon pairing to a spin-nematic state.
