Rare events in population genetics: Stochastic tunneling in a two-locus model with recombination
Alexander Altland, Andrej Fischer, Joachim Krug +1
We study the evolution of a population in a two-locus genotype space, in which the negative effects of two single mutations are overcompensated in a high fitness double mutant. We…
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…
Records and sequences of records from random variables with a linear trend
Jasper Franke, Gregor Wergen, Joachim Krug
We consider records and sequences of records drawn from discrete time series of the form , where the are independent and identically distributed random vari…
Record-breaking temperatures reveal a warming climate
Gregor Wergen, Joachim Krug
We present a mathematical analysis of records drawn from independent random variables with a drifting mean. To leading order the change in the record rate is proportional to the ra…
Anti-Coarsening and Complex Dynamics of Step Bunches on Vicinal Surfaces during Sublimation
Marian Ivanov, Vladislav Popkov, Joachim Krug
A sublimating vicinal crystal surface can undergo a step bunching instability when the attachment-detachment kinetics is asymmetric, in the sense of a normal Ehrlich-Schwoebel effe…
Evolutionary advantage of small populations on complex fitness landscapes
Kavita Jain, Joachim Krug, Su-Chan Park
Background: Recent experimental and theoretical studies have shown that small asexual populations evolving on complex fitness landscapes may achieve a higher fitness than large one…
