Fractal structure of a three dimensional Brownian motion on an attractive plane
dimensional Brownian motion Statistical Mechanics Mathematical Physics
2011/10/9
Abstract: Consider a Brownian particle in three dimensions which is attracted by a plane with a strength proportional to some dimensionless parameter $\alpha$. We investigate the fractal spatial struc...
Frozen shuffle update for an asymmetric exclusion process with open boundary conditions
pedestrian traffic exclusion process shuffle update boundary driven phase transition
2011/8/17
Abstract: We introduce a new update algorithm for exclusion processes, more suitable for the modeling of pedestrian traffic. Pedestrians are modeled as hard-core particles hopping on a discrete lattic...
How universal is the Wigner distribution?
Wigner distribution High Energy Physics - Theory Statistical Mechanics Probability
2011/10/9
Abstract: We consider Gaussian ensembles of m N x N complex matrices. We identify an enhanced symmetry in the system and the resultant closed subsector, which is naturally associated with the radial s...
Generic Ising Trees
Generic Ising Trees Statistical Mechanics High Energy Physics - Theory
2011/10/8
Abstract: The Ising model on an infinite generic tree is defined as a thermodynamic limit of finite systems. A detailed description of the corresponding distribution of infinite spin configurations is...
Relaxation rate of the reverse biased asymmetric exclusion process
asymmetric exclusion process Statistical Mechanics
2011/10/8
Abstract: We compute the exact relaxation rate of the partially asymmetric exclusion process with open boundaries, with boundary rates opposing the preferred direction of flow in the bulk. This revers...
Information Symmetries in Irreversible Processes

2011/9/30
Abstract: We study dynamical reversibility in stationary stochastic processes from an information theoretic perspective. Extending earlier work on the reversibility of Markov chains, we focus on finit...
Parrondo-like behavior in CTRWs with memory
Parrondo-like behavior CTRWs memory Statistical Mechanics
2011/9/5
Abstract: The Continuous-Time Random Walk (CTRW) formalism can be adapted to encompass stochastic processes with memory. In this letter we will show how the random combination of two different unbiase...
Abstract: An implementation of BFACF-style algorithms on knotted polygons in the simple cubic, face centered cubic and body centered cubic lattice is used to estimate the statistics and writhe of mini...
Interface growth in the channel geometry and tripolar Loewner evolutions
channel geometry tripolar Loewner evolutions Interface growth Statistical Mechanics
2011/9/30
Abstract: A class of Laplacian growth models in the channel geometry is studied using the formalism of tripolar Loewner evolutions, in which three points, namely, the channel corners and infinity, are...
A scale-invariant probabilistic model based on Leibniz-like pyramids
scale-invariant probabilistic model Leibniz-like pyramids Statistical Mechanics
2011/9/29
Abstract: We introduce a family of probabilistic {\it scale-invariant} Leibniz-like pyramids and $(d+1)$-dimensional hyperpyramids ($d=1,2,3,...$), characterized by a parameter $\nu>0$, whose value de...
We study the morphology of watersheds in two and three dimensional systems subjected to different degrees of spatial correlations. The response of these objects to small, local perturbations is also i...
The principle of absence of arbitrage opportunities allows obtaining the distribution of stock price fluctuations by maximizing its information entropy. This leads to a physical description of the und...
Stochastic dynamics of an electron in a Penning trap: phase flips correlated with amplitude collapses and revivals
Stochastic dynamics electron amplitude
2011/9/28
We study the effect of noise on the axial mode of an electron in a Penning trap under parametric-resonance conditions. Our approach, based on the application of averaging techniques to the description...
Markov processes follow from the principle of Maximum Caliber
principle Maximum Caliber Markov
2011/9/14
Markov models are widely used to describe processes of stochastic dynamics. Here, we show that Markov models are a natural consequence of the dynamical principle of Maximum Caliber. First, we show tha...
Emergence, Reduction and Supervenience: a Varied Landscape
A Varied Landscape supervenience
2011/8/29
This is one of two papers about emergence, reduction and supervenience. It expounds these notions and analyses the general relations between them. The companion paper analyses the situation in physics...
