Abstract

A permutation group approach to a one-dimensional Heisenberg open spin-1/2 chain with nearest neighbor interactions is studied. Regular fractal structures appear in matrices of the Hamiltonian constructed under the outer-product basis of the permutation group, which enables one to solve the eigenvalue problem in a systematic manner.
