摘要
The level statistics in the two dimensional disordered electron systems in magnetic fields (unitary ensemble) or in the presence of strong spin-orbit scattering (symplectic ensemble) are investigated at the Anderson transition points. The level spacing distribution functions 's are found to be independent of the system size or of the type of the potential distribution, suggesting the universality. They behave as in the small region in the former case, while rise is seen in the latter.
