Molecular magnetism,rms. Studying such finite spin systems focuses on qualitatively new physics caused by the finite size of the system. Among the findings discussed in this chapter are extensions of the theorems of Lieb, Schultz, and Mattis, the introduction of rotational bands as well as the discovery of giant magnetization jumps.

南極

Spin wave analysis of heisenberg magnets in restricted geometries, applications in lowspace dimensionality as well as some recent modifications of the theory admitting a quantitative analysis in magnetically disordered phases. The presented spin-wave results are compared with available numerical estimates.

Integrability of quantum chains: Theory and applications to the spin-1/2 , chain,thod, is carried out for the seminal model of the spin-1/2 . chain for which thermodynamic properties like specific heat, magnetic susceptibility and the finite temperature Drude weight of the thermal conductivity are derived.

One-dimensional magnetism,d real materials. Main emphasis of the chapter is on quantum phenomena in models of localized spins with isotropic exchange and additional interactions from anisotropy and external magnetic fields..Three sections deal with the main classes of model systems for 1D quantum magnetism: .=1/2 chains, spi

,Quantum magnetism in two dimensions: From semi-classical Néel order to magnetic disorder,till be destroyed e.g. by quantum fluctuations or geometric frustration. In this context, we review ground-state features of the .=1/2 Heisenberg antiferromagnet on two-dimensional lattices. In order to discuss the interplay of lattice topology and quantum fluctuations we focus on the 11 two-dimensi
