| Outline of Final Research Achievements |
Using extensive numerical simulations, this project has contributed to a better understanding of the critical phenomena of the Anderson transition both in simplified models, and in more realistic models of the metal-insulator transition in doped semiconductors. We studied the dimensionality dependence of the critical exponent of the Anderson transition in simplified models in detail numerically and found the results to be in reasonable agreement with analytical predictions. We also studied the effect of magnetic impurities on the Anderson transition and found the results to be consistent with analytical theoretical predictions. We also found evidence that the critical exponent (and hence the universality class of the phase transition) is changed by the long-range Coulomb interaction between electrons.
