Abstract:
In this thesis, we have studied some exact solutions for low dimensional strongly correlated systems, especially spin chains. In the first chapter using simple AKLT model and introducing Valence Bond Solid States we have prepared good area to study Finitely Correlated States. In addition to presenting relation between these concepts, we have expressed Matrix Product States as a simpler formalism to deal with Finitely Correlated States. In the second chapter we have discussed the Optimum Ground State concept and we have studied a spin-32 with nearest neighbor interaction and a spin-1 model with next nearest neighbor interaction
as example
