Outline of Final Research Achievements |
I have studied how disorders in materials affect the physical phenomenon. In particular, it is proved that the Anderson model, which is supposed to describe the state of an electron in disordered media, can be approximated by the homogeneous model in a certain scaling. Moreover, the scale and nature of the fluctuation caused by random disorder is determined in detail. Aside from this, a polymer model in a disordered solvent is also studied. In the limit of strong disorder, it is shown that the model can be approximated by another natural and simple model.
