Susy atomic model

J. Hopkinson, P. Coleman

We present the simplest model to which one can apply the supersymmetric Hubbard operators recently introduced. For the atomic model, $H = - E_{d} X_{00}$ , where $X_{00} = ∣0 >< 0∣$ is a H…

Atomic Model of Susy Hubbard Operators

John Hopkinson, Piers Coleman

We apply the recently proposed susy Hubbard operators to an atomic model. In the limiting case of free spins, we derive exact results for the entropy which are compared with a mean…
