A new quantum phase in two dimensions
Giuliano Benenti, Xavier Waintal, Jean-Louis Pichard
For intermediate Coulomb energy to Fermi energy ratios , spinless fermions in a random potential form a new quantum phase which is different from the Fermi glass and the Wigne…

Quantum opening of the Coulomb gap in two dimensions
Giuliano Benenti, Xavier Waintal, Jean-Louis Pichard +1
For a constant density of spinless fermions in strongly disordered two dimensional clusters, the energy level spacing between the ground state and the first excitation is studied f…
