Abstract

We describe a few properties of the XXX spin chain with long range interaction. The plan of these notes is:
  1. 1

    — The Hamiltonian.

     
  2. 2

    — Symmetry of the model.

     
  3. 3

    — The irreducible multiplets.

     
  4. 4

    — The spectrum.

     
  5. 5

    — Wave functions and statistics.

     
  6. 6

    — The spinon description.

     
  7. 7

    — The thermodynamics.
