Martina Hentschel 1, Denis Ullmo 1, 2, Harold U. Baranger 1 Physical Review Letters 93 (2004) 176807 We study the x-ray edge problem for a chaotic quantum dot or nanoparticle displaying mesoscopic fluctuations. In the bulk, x-ray physics is known to produce deviations from the naively expected photoabsorption cross section in the form of a peaked or rounded edge. For a coherent system […]

A. C. Bertuola 1, O. Bohigas 2, M. P. Pato 1 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 70 (2004) 065102 Using the Generalized Maximium Entropy Principle based on the nonextensive q entropy a new family of random matrix ensembles is generated. This family unifies previous extensions of Random Matrix Theory and gives rise to an orthogonal invariant stable

Martin R. Evans 1, Satya Majumdar 2, 3, Royce K.P. Zia 4, 5 Journal of Physics A 37 (2004) L275-L280 We study a class of mass transport models where mass is transported in a preferred direction around a one-dimensional periodic lattice and is globally conserved. The model encompasses both discrete and continuous masses and parallel and random sequential dynamics and includes models such as the

Shu-Chiuan Chang 1, 2, Jesper-Lykke Jacobsen 3, Jesus Salas 4, 5, Robert Shrock 1 Journal of Statistical Physics 114 (2004) 763-823 We present exact calculations of the Potts model partition function Z(G,q,v) for arbitrary q and temperature-like variable v on n-vertex strip graphs G of the triangular lattice for a variety of transverse widths equal to L vertices and for arbitrarily great length equal to

Satya Majumdar 1, Alain Comtet 2, 3 Physical Review Letters 92 (2004) 225501 We present an exact solution for the distribution P(h_m,L) of the maximal height h_m (measured with respect to the average spatial height) in the steady state of a fluctuating Edwards-Wilkinson interface in a one dimensional system of size L with both periodic and free boundary conditions. For

Hong Jiang 1, 2, 3, Denis Ullmo 2, 4, Weitao Yang 1, Harold U. Baranger 2 Physical Review B 69 (2004) 235326 We use Kohn-Sham spin-density-functional theory to study the statistics of ground-state spin and the spacing between conductance peaks in the Coulomb blockade regime for both 2D isolated and realistic quantum dots. We make a systematic investigation of the effects of electron-electron interaction strength and electron

Antonio M. Garcia-Garcia 1 Physical Review B 69 (2004) 245121 We study the effect of a magnetic flux in a 1D disordered wire with long range hopping. It is shown that this model is at the metal-insulator transition (MIT) for all disorder values and the spectral correlations are given by critical statistics. In the weak disorder regime a
