Antiferromagnetic Spin Waves, 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

Spin-Wave Theory,er we describe a much more general method, due originally to Anderson, which is widely used to obtain results for many different systems. It is referred to as ‘spin-wave theory’ as it gives results for the energies of the elementary excitations or spin waves. The method works for both ferromagnets a

Numerical Finite-Size Calculations,h 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
