Factorised Steady States in Mass Transport Models

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 […]

Exact Potts Model Partition Functions for Strips of the Triangular Lattice

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

Exact Maximal Height Distribution of Fluctuating Interfaces

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

Electron-Electron Interactions in Isolated and Realistic Quantum Dots: A Density Functional Theory Study

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

Effect of a magnetic flux on the critical behavior of a system with long range hopping

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

Cooperativity in two-state protein folding kinetics

Thomas R. Weikl 1, 2, Matteo Palassini 1, 3, Ken A. Dill 1 Protein Science 13 (2004) 822-829 We present a solvable model that predicts the folding kinetics of two-state proteins from their native structures. The model is based on conditional chain entropies. It assumes that folding processes are dominated by small-loop closure events that can be inferred from native structures. For CI2,
