Stretched exponential behavior and random walks on diluted hypercubic lattices
N. Lemke, I. A. Campbell
Diffusion on a diluted hypercube has been proposed as a model for glassy relaxation and is an example of the more general class of stochastic processes on graphs. In this article w…
Micellization in the presence of polyelectrolyte
N. Lemke, Jeferson J. Arenzon, Yan Levin
We present a simple model to study micellization of amphiphiles condensed on a rodlike polyion. Although the mean field theory leads to a first order micellization transition for s…
Stretched Exponential Relaxation on the Hypercube and the Glass Transition
R. M. C. de Almeida, N. Lemke, I. A. Campbell
We study random walks on the dilute hypercube using an exact enumeration Master equation technique, which is much more efficient than Monte Carlo methods for this problem. For each…
Finite temperature phase transition in the two-dimension Randomly Coupled Ferromagnet
N. Lemke, I. A. Campbell
We show using extensive simulation results and physical arguments that an Ising system on a two dimensional square lattice, having interactions of random sign between first neighbo…
The Spin Glass Transition : Exponents and Dynamics
L. W. Bernardi, N. Lemke, P. O. Mari +3
Numerical simulations on Ising Spin Glasses show that spin glass transitions do not obey the usual universality rules which hold at canonical second order transitions. On the other…
Chaotic Dynamics of High Order Neural Networks
N. Lemke, J. J. Arenzon, F. A. Tamarit
The dynamics of an extremely diluted neural network with high order synapses acting as corrections to the Hopfield model is investigated. As in the fully connected case, the high o…
