| Research Abstract |
One of the typical properties of the random Schroedinger operators is that the density of states decays exponentially. In our work, we reveal the transition of this behavior as the variation of the strength of the randomness and the potential. Another typical more well- known property is the Anderson localization. In our work, we extend the mathematical proof of the existence of this localization to the case that the magnetic field is a Gaussian random field, which is the most fundamental and natural random field.
