Quasi-classical localized states in the 2D ferrimagnet

Quasi-classical localized states in the 2D ferrimagnet

We consider highly anisotropic 2D quantum s = 1/2 (pseudo)magnetic system which is equivalent to the frequently used system of charged hard-core bosons on a square lattice. In the continuous quasi-classical approximation, the types of localized excitations are determined by asymptotic analysis and c...
