A. Das et C. Wotzasek, 2-DIMENSIONAL SUPERSYMMETRIC HARMONIC-OSCILLATOR CARRYING A REPRESENTATION OF THE GL(2 1) GRADED LIE-ALGEBRA/, Journal of mathematical physics, 37(1), 1996, pp. 61-71
We study a supersymmetric two-dimensional harmonic oscillator which ca
rries a representation of the general graded Lie algebra GL(2/1), form
ulate it on the superspace, and discuss its physical spectrum. (C) 199
