Employing the chiral Gaussian unitary ensemble of random matrices, we calculate the probability distribution of the local density of states for zero-dimensional ("quantum chaotic") two-sublatticeâ€¦ (More)

â€“ We investigate the distribution of the resonance widths P(Î“) and Wigner delay times P(Ï„W) for scattering from two-dimensional systems in the diffusive regime. We obtain the forms of theseâ€¦ (More)

We study level-number variance in a two-dimensional random matrix model characterized by a power-law decay of the matrix elements. The amplitude of the decay is controlled by the parameter b. We findâ€¦ (More)

We calculate the density of states of electron-hole excitations in a superconductorâ€“normal-metalâ€“ superconductor SNS junction in graphene, in the long-junction regime that the superconducting gap 0â€¦ (More)

We investigate the statistics of eigenfunction intensities P(/psi/(2)) in dynamical systems with classical chaotic diffusion. Our results contradict some recent theoretical considerations thatâ€¦ (More)

We consider a simple model of quantum disorder in two dimensions, characterized by a long-range site-to-site hopping. The system undergoes a metalâ€“insulator transition--its eigenfunctions change fromâ€¦ (More)

We consider a two-dimensional (2D) generalization of the standard kicked rotor and show that it is an excellent model for the study of universal features of 2D quantum systems with underlyingâ€¦ (More)

We develop a novel approach to the Anderson localization problem in a d-dimensional disordered sample of dimension LÃ—M^{d-1}. Attaching a perfect lead with the cross section M^{d-1} to one side ofâ€¦ (More)

We study the proximity effect of a superconductor to a normal system with a fractal spectrum. We find that there is no gap in the excitation spectrum, even in the case where the underlying classicalâ€¦ (More)
