0075-8450 ntary material: The topic of lattice quantum spin systems is a fascinating and by nowwell-established branch of theoretical physics. However, many important questions remain to be answered. Their intrinsically quantum mechanical nature and the large (usually effectively infinite) number of spins in

Introduction,r interactions (quantum spin systems). The nature of the exchange interaction is discussed, and we distinguish between ferromagnetic and antiferromagnetic coupling. Finally we summarise the contents of subsequent chapters.

Once the fundamental integral equation has been derived it is solved by Fourier transform. Finally the solution . is used to find the antiferromagnetic ground-state energy.
