Time evolutions of the logarithm of the length of the pseudo-spin polarization vector for the graph of different sites. The parameters are \(\bar{J}=1\) and \(\bar{ {\mathcal E} }=1000\). The initial states are |1, −〉 for the graph of three sites (n = 1), \((|2,-\,\rangle +|1,-\,\rangle )/\sqrt{2}\) for the graph of five sites (n = 2).
