Branching with selection and mutation II: Mutant fitness of Gumbel type
Su-Chan Park, Joachim Krug, Peter Mörters
We study a model of a branching process subject to selection, modeled by giving each family an individual fitness acting as a branching rate, and mutation, modeled by resampling th…
Coarsening of Sand Ripples in Mass Transfer Models with Extinction
E. K. O. Hellén, J. Krug
Coarsening of sand ripples is studied in a one-dimensional stochastic model, where neighboring ripples exchange mass with algebraic rates, , and ripples of zero mass…
Pattern Dynamics of Vortex Ripples in Sand: Nonlinear Modeling and Experimental Validation
K. H. Andersen, M. Abel, J. Krug +3
Vortex ripples in sand are studied experimentally in a one-dimensional setup with periodic boundary conditions. The nonlinear evolution, far from the onset of instability, is analy…
Comment on ``Determination of Interlayer Diffusion Parameters for Ag(111)''
Joachim Krug
A Comment on PRL 85, 1480 (2000) by K.R. Roos and M.C. Tringides.
Asymmetric particle systems on R
J. Krug, J. Garcia
We study interacting particle systems on the real line which generalize the Hammersley process [D. Aldous and P. Diaconis, Prob. Theory Relat. Fields 103, 199-213 (1995)]. Particle…
Fast coarsening in unstable epitaxy with desorption
Pavel Smilauer, Martin Rost, Joachim Krug
Homoepitaxial growth is unstable towards the formation of pyramidal mounds when interlayer transport is reduced due to activation barriers to hopping at step edges. Simulations of…
Persistence exponents for fluctuating interfaces
J. Krug, H. Kallabis, S. N. Majumdar +3
Numerical and analytic results for the exponent θdescribing the decay of the first return probability of an interface to its initial height are obtained for a large class of linear…
