摘要: Abstract The exact eigenstates and eigenvalues of a linear ring 16 spins described by Heisenberg Hamiltonian with first- second-neighbor interactions have been calculated. method used is basedon hierarchy algebras. In the present paper ground state density states for various values relative strength interaction are presented. Some interesting features certain parameters appear.
