Does a magnetic field modify the critical behaviour at the metal-insulator transition in 3-dimensional disordered systems?
E. Hofstetter, M. Schreiber
The critical behaviour of 3-dimensional disordered systems with magnetic field is investigated by analyzing the spectral fluctuations of the energy spectrum. We show that in the th…

Shape Analysis of the Level Spacing Distribution around the Metal Insulator Transition in the Three Dimensional Anderson Model
Imre Varga, Etienne Hofstetter, Michael Schreiber +1
We present a new method for the numerical treatment of second order phase transitions using the level spacing distribution function . We show that the quantities introduced o…

Relation between Energy Level Statistics and Phase Transition and its Application to the Anderson Model
E. Hofstetter, M. Schreiber
A general method to describe a second-order phase transition is discussed. It starts from the energy level statistics and uses of finite-size scaling. It is applied to the metal-in…
