Besondere Herstellungsverfahren, reversed. The elementary excitations from the ground state have . spins reversed. To calculate the energies of these states, des Cloiseaux and Pearson used a modified version of the same method that Hulthén had used for the ground state energy. The modifications are quite significant and involve so

However the mathematical techniques involved here are not based on the Bethe Ansatz, but instead use a Jordan-Wigner transformation. The first step is t

Maschinen für das Zusammenfügen der Theileh make use of sophisticated approximation techniques developed in many areas of quantum many-body theory. However, in this chapter we first look a very simple numerical method that does not involve any theory other than the assumption that the properties of small systems change smoothly as the size
