Abstract
The exact statistical mechanics of a one-dimensional gas of particles is presented. Each particle has a classical vector spin, and nearest neighbour particles interact via spin-independent and spin-dependent forces. In zero external magnetic field, the resultant eigenvalue problem is solved and, for a particular choice of interactions, the model is studied in some detail, including an analysis of a variety of possible ground states.Keywords
