Interacting quantum spin chains. [Invited paper for the International Conference on Neutron Scattering ICNS-2001.]
Abstract
Description
A brief review of recent advances in neutron scattering studies of low-dimensional quantum magnets is followed by a particular example. The separation of single-particle and continuum states in the weakly-coupled $S=1/2$ chains system BaCu2Si2O7 is described in some detail.
