Distribution of repetitions of ancestors in genealogical trees
B. Derrida, S. C. Manrubia, D. H. Zanette
We calculate the probability distribution of repetitions of ancestors in a genealogical tree for simple neutral models of a closed population with sexual reproduction and non-overl…
Very long transients in globally coupled maps
S. C. Manrubia, A. S. Mikhailov
Very long transients are found in the partially ordered phase of type II of globally coupled logistic maps. The transients always lead the system in this phase to a state with a fe…
Stable and Metastable Structures of Cobalt on Cu(001): An ab initio Study
R. Pentcheva, M. Scheffler
We report results of density-functional theory calculations on the structural, magnetic, and electronic properties of (1x1)-structures of Co on Cu(001) for coverages up to two mono…
Finite Wavelength Instabilities in a Slow Mode Coupled Complex Ginzburg-Landau Equation
M. Ipsen, P. G. Soerensen
In this letter, we discuss the effect of slow real modes in reaction-diffusion systems close to a supercritical Hopf bifurcation. The spatio-temporal effects of the slow mode canno…
Towards a first-principles theory of surface thermodynamics and kinetics
C. Stampfl, H. J. Kreuzer, S. H. Payne +2
Understanding of the complex behavior of particles at surfaces requires detailed knowledge of both macroscopic and microscopic processes that take place; also certain processes dep…
Noise-induced breakdown of coherent collective motion in swarms
A. S. Mikhailov, D. H. Zanette
We consider swarms formed by populations of self-propelled particles with attractive long-range interactions. These swarms represent multistable dynamical systems and can be found…
Equilibrium shapes and energies of coherent strained InP islands
Q. K. K. Liu, N. Moll, M. Scheffler +1
The equilibrium shapes and energies of coherent strained InP islands grown on GaP have been investigated with a hybrid approach that has been previously applied to InAs islands on…
Density-functional theory study of the catalytic oxidation of CO over transition metal surfaces
C. Stampfl, M. Scheffler
In recent years due to improvements in calculation methods and increased computer power, it has become possible to perform first-principles investigations for ``simple'' chemical r…
Formation and stability of self-assembled coherent islands in highly mismatched heteroepitaxy
L. G. Wang, P. Kratzer, M. Scheffler +1
We study the energetics of island formation in Stranski-Krastanow growth within a parameter-free approach. It is shown that an optimum island size exists for a given coverage and i…
Exchange and Correlation Kernels at the Resonance Frequency -- Implications for Excitation Energies in Density-Functional Theory
X. Gonze, M. Scheffler
Specific matrix elements of exchange and correlation kernels in time-dependent density-functional theory are computed. The knowledge of these matrix elements not only constraints a…
Model for nucleation in GaAs homoepitaxy derived from first principles
P. Kratzer, C. G. Morgan, M. Scheffler
The initial steps of MBE growth of GaAs on beta 2-reconstructed GaAs(001) are investigated by performing total energy and electronic structure calculations using density functional…
Mutual synchronization and clustering in randomly coupled chaotic dynamical networks
Susanna C. Manrubia, Alexander S. Mikhailov
We introduce and study systems of randomly coupled maps (RCM) where the relevant parameter is the degree of connectivity in the system. Global (almost-) synchronized states are fou…
Universality of the Hohenberg-Kohn functional
Arno Schindlmayr
We comment on a recent article by H. L. Neal [Am. J. Phys. 66, 512 (1998)], in which an analytic expression for the Hohenberg-Kohn functional was derived for one-dimensional two-pa…
Improving the Efficiency of FP-LAPW Calculations
Max Petersen, Frank Wagner, Lars Hufnagel +3
The full-potential linearized augmented-plane wave (FP-LAPW) method is well known to enable most accurate calculations of the electronic structure and magnetic properties of crysta…
Stochastic multiplicative processes with reset events
Susanna C. Manrubia, Damian H. Zanette
We study a stochastic multiplicative process with reset events. It is shown that the model develops a stationary power-law probability distribution for the relevant variable, whose…
Statistical properties of genealogical trees
Bernard Derrida, Susanna C. Manrubia, Damian H. Zanette
We analyse the statistical properties of genealogical trees in a neutral model of a closed population with sexual reproduction and non-overlapping generations. By reconstructing th…
