M. Moshinsky et al., SUPERSYMMETRY AND SUPERALGEBRA FOR THE 2-BODY SYSTEM WITH A DIRAC OSCILLATOR INTERACTION, Journal of physics. A, mathematical and general, 28(22), 1995, pp. 6447-6457
Some years ago, one of the authors (MM) revived a concept to which he
gave the name single-particle Dime oscillator, while another of the au
thors (CQ) showed that it corresponds to a realization of supersymmetr
ic quantum mechanics. The Dirac oscillator in its one- and many-body v
ersions has had a great number of applications. Recently, it included
the analytic expression for the eigenstates and eigenvalues of a two-p
article system with a new type of Dirac oscillator interaction of freq
uency omega. By considering the latter together with its partner corre
sponding to the replacement of omega by -omega, we are able to get a s
upersymmetric formulation of the problem and find the superalgebra tha
t explains its degeneracy.
