Diffusion-limited reactions on disordered surfaces with continuous distributions of binding energies
A. Wolff, I. Lohmar, J. Krug +1
We study the steady state of a stochastic particle system on a two-dimensional lattice, with particle influx, diffusion and desorption, and the formation of a dimer when particles…
Switching between phenotypes and population extinction
Ingo Lohmar, Baruch Meerson
Many types of bacteria can survive under stress by switching stochastically between two different phenotypes: the "normals" who multiply fast, but are vulnerable to stress, and the…
Diffusion-limited reactions on a two-dimensional lattice with binary disorder
A. Wolff, I. Lohmar, J. Krug +2
Reaction-diffusion systems where transition rates exhibit quenched disorder are common in physical and chemical systems. We study pair reactions on a periodic two-dimensional latti…
Interaction of Atomic and Molecular Hydrogen with Tholin Surfaces at Low Temperatures
Ling Li, Hui Zhao, Gianfranco Vidali +4
We study the interaction of atomic and molecular hydrogen with a surface of tholin, a man-made polymer considered to be an analogue of aerosol particles present in Titan's atmosphe…
Accurate rate coefficients for models of interstellar gas-grain chemistry
Ingo Lohmar, Joachim Krug, Ofer Biham
The methodology for modeling grain-surface chemistry has been greatly improved by taking into account the grain size and fluctuation effects. However, the reaction rate coefficient…
Diffusion-limited reactions and mortal random walkers in confined geometries
Ingo Lohmar, Joachim Krug
Motivated by the diffusion-reaction kinetics on interstellar dust grains, we study a first-passage problem of mortal random walkers in a confined two-dimensional geometry. We provi…
