Marshall-Peierls sign rule for excited states of the frustrated J1− J2 Heisenberg antiferromagnet

We present analytical and numerical calculations for some excited states of the frustrated J 1− J 2 spin- 1 2 Heisenberg model for linear chains and square lattices. We consider the lowest eigenstates in the subspaces determined by the eigenvalue M of the spin operator S total z . Because of the red...
