Metal-Insulator Transition in Randomly Interacting Systems
B. Rosenow, R. Oppermann
We discuss a metal-insulator transition caused by random couplings of magnetic moments in itinerant systems. An analytic solution for the single particle Green function is derived…

Studies of the phase diagram of randomly interacting fermionic systems
R. Oppermann, B. Rosenow
We present details of the phase diagrams of fermionic systems with random and frustrated interactions, emphasizing the important role of the chemical potential. The insulating ferm…
