We discuss several applications and extensions of our previous operato
r solution of the N-body quantum-mechanical Calogero problem, i.e. N p
articles in one dimension subject to a two-body interaction of the for
m 1/2SIGMA(i,j) [(x(i) - x(j))2 + g/(x(i) - x(j))2]. Using a complex r
epresentation of the deformed Heisenberg algebra underlying the Caloge
ro model, we explicitly establish the equivalence between this system
and anyons in the lowest Landau level. A construction based on supersy
mmetry is used to extend our operator method to include fermions, and
we obtain an explicit solution of the supersymmetric Calogero model co
nstructed by Freedman and Mende. We also show how the dynamical OSp(2;
2) supersymmetry is realized by bilinears of modified creation and an
nihilation operators, and how to construct a supersymmetic extension o
f the deformed Heisenberg algebra.
