Giant fluctuations at a granular phase separation threshold
Baruch Meerson, Thorsten Poeschel, Pavel V. Sasorov +1
We investigate a phase separation instability that occurs in a system of nearly elastically colliding hard spheres driven by a thermal wall. If the aspect ratio of the confining bo…
Entropy and Long range correlations in literary English
Werner Ebeling, Thorsten Poeschel
We investigated long range correlations in two literary texts, Moby Dick by H. Melville and Grimm's tales. The analysis is based on the calculation of entropy like quantities as th…
Synchronization effects in the dynamical behavior of elevators
Thorsten Poeschel, Jason A. C. Gallas
We simulate the dynamical behavior of M elevators serving N floors of a building in which a Poisson distribution of persons call elevators. Our simulation reproduces the jamming ef…
A model for collisions in granular gases
Nikolai V. Brilliantov, Frank Spahn, Jan-Martin Hertzsch +1
We propose a model for collisions between particles of a granular material and calculate the restitution coefficients for the normal and tangential motion as functions of the impac…
Simulation of rotating drum experiments using non-circular particles
Volkhard Buchholtz, Thorsten Poeschel, Hans-Juergen Tillemans
We investigate the flow of granular material in a rotating cylinder numerically using molecular dynamics in two dimensions. The particles are described by a new model which allows…
Guessing probability distributions from small samples
Thorsten Poeschel, Werner Ebeling, Helge Rose
We propose a new method for the calculation of the statistical properties, as e.g. the entropy, of unknown generators of symbolic sequences. The probability distribution p(k) of th…
A Statistical Approach to Vehicular Traffic
Jan Freund, Thorsten Poeschel
A two-dimensional cellular automaton is introduced to model the flow and jamming of vehicular traffic in cities. Each site of the automaton represents a crossing where a finite num…
Avalanche statistics of sand heaps
Volkhard Buchholtz, Thorsten Poeschel
Large scale computer simulations are presented to investigate the avalanche statistics of sand piles using molecular dynamics. We could show that different methods of measurement l…
Swirling Granular Matter: From Rotation to Reptation
Michael A. Scherer, Volkhard Buchholtz, Thorsten Poeschel +1
A novel effect in a granular material under swirling motion of the container is presented. At low packing densities the material rotates in the same direction as the swirling motio…
Scaling properties of granular materials
Thorsten Poeschel, Clara Saluena, Thomas Schwager
Given an assembly of viscoelastic spheres with certain material properties, we raise the question how the macroscopic properties of the assembly will change if all lengths of the s…
Finite-sample frequency distributions originating from an equiprobability distribution
Thorsten Poeschel, Jan A. Freund
Given an equidistribution for probabilities p(i)=1/N, i=1..N. What is the expected corresponding rank ordered frequency distribution f(i), i=1..N, if an ensemble of M events is dra…
Molecular Dynamics of Comminution in Ball Mills
Volkhard Buchholtz, Jan A. Freund, Thorsten Poeschel
We investigate autogenous fragmentation of dry granular material in rotating cylinders using two-dimensional molecular dynamics. By evaluation of spatial force distributions achiev…
Rolling as a continuing collision
Nikolai V. Brilliantov, Thorsten Poeschel
We show that two basic mechanical processes, the collision of particles and rolling motion of a sphere on a plane, are intimately related. According to our recent findings, the res…
