Abstract
A decimation approach to the electronic properties of three-dimensional systems with both strong electron-electron interactions and randomness is developed and applied to the Hubbard model with disorder. To probe the nature of many-body eigenstates, the authors have calculated the energy gap, localisation of states, magnitude of local spin moments as well as low-lying excitation spectra from which the phase diagram is discussed.Keywords
