| Research Abstract |
Numerical simulations of the Anderson transition and Anderson localization in 3D, 2D and fractal systems were performed. We confirmed that the lower critical dimension of the Anderson transition for Hamiltonians with symplectic symmetry is less than two. We obtained a precise estimate of the critical exponent for the Anderson transition in the integer Quantum Hall Effect.
