摘要：
We study the applicability of composite-fermion theory to electrons in two-dimensional parabolically confined quantum dots in a strong perpendicular magnetic field in the limit of low Zeeman energy. The noninteracting composite fermion spectrum correctly specifies the primary features of this system. Additional features are relatively small, indicating that the residual interaction between the composite fermions is weak.
