Transition to an Insulating Phase Induced by Attractive Interactions in the Disordered Three-Dimensional Hubbard Model
Bhargavi Srinivasan, Giuliano Benenti, Dima L. Shepelyansky
We study numerically the interplay of disorder and attractive interactions for spin-1/2 fermions in the three-dimensional Hubbard model. The results obtained by projector quantum M…
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…
3D Anderson transition for two electrons in 2D
D. L. Shepelyansky
It is shown that the Coulomb interaction can lead to delocalization of two electron states in two-dimensional (2D) disordered potential in a way similar to the Anderson transition…
Quantum Fractal Eigenstates
Giulio Casati, Giulio Maspero, Dima L. Shepelyansky
We study quantum chaos in open dynamical systems and show that it is characterized by quantum fractal eigenstates located on the underlying classical strange repeller. The states w…
