Adaptive walks on time-dependent fitness landscapes
Claus O. Wilke, Thomas Martinetz
The idea of adaptive walks on fitness landscapes as a means of studying evolutionary processes on large time scales is extended to fitness landscapes that are slowly changing over…
Aftershocks in Coherent-Noise Models
C. Wilke, S. Altmeyer, T. Martinetz
The decay pattern of aftershocks in the so-called 'coherent-noise' models [M. E. J. Newman and K. Sneppen, Phys. Rev. E54, 6226 (1996)] is studied in detail. Analytical and numeric…
A Simple Model of Evolution with Variable System Size
C. Wilke, T. Martinetz
A simple model of biological extinction with variable system size is presented that exhibits a power-law distribution of extinction event sizes. The model is a generalization of a…
Axion cyclotron emissivity of magnetized white dwarfs and neutron stars
M. Kachelriess, C. Wilke, G. Wunner
The energy loss rate of a magnetized electron gas emitting axions a due to the process is derived for arbitrary magnetic field strength B. Requiring that for a str…
Photon splitting in strong magnetic fields: asymptotic approximation formulae vs. accurate numerical results
C. Wilke, G. Wunner
We present the results of a numerical calculation of the photon splitting rate below the electron-pair creation threshold () in magnetic fields $B ~{> \atop \sim}~ B_{\rm…
