Аннотация: Using the diagram technique for spin operators, the exact representations for quantum magnets are obtained that express the Green's functions via the components of mass operator ??? end factors L and Q, and the Larkin-and Dyson-irreducible part T- irr.The elementary excitation spectrum and mean magnetization are calculated accurateПоказать полностьюto the first-order contributions on the parameter r0 -3 by the self-consistent field method. © 2012 Allerton Press, Inc.
