Abstract

Abstract The energy spectrum and wave functions are studied for an N×N cluster in a system with one hole and one flipped spin. The calculation is made for given values of the total quasimomentum α of the system. A system of four nonlinear algebraic equations for determining the energy levels of the system is obtained. The analysis is restricted to the simplest case α x= α y=(0, π).
