Non-Arrhenius Behavior of Surface Diffusion Near a Phase Transition Boundary
I. Vattulainen, J. Merikoski, T. Ala-Nissila +1
We study the non-Arrhenius behavior of surface diffusion near the second-order phase transition boundary of an adsorbate layer. In contrast to expectations based on macroscopic the…
A Dynamical Mean Field Theory for the Study of Surface Diffusion Constants
T. Hjelt, I. Vattulainen, J. Merikoski +2
We present a combined analytical and numerical approach based on the Mori projection operator formalism and Monte Carlo simulations to study surface diffusion within the lattice-ga…
Non-equilibrium surface diffusion in the O/W(110) system
I. Vattulainen, J. Merikoski, T. Ala-Nissila +1
In this Letter, we present results of an extensive Monte Carlo study of the O/W(110) system under non-equilibrium conditions. We study the mean square displacements and long wavele…
Physical tests for Random Numbers in Simulations
I. Vattulainen, T. Ala-Nissila, K. Kankaala
We propose three physical tests to measure correlations in random numbers used in Monte Carlo simulations. The first test uses autocorrelation times of certain physical quantities…
Bit Level Correlations in Some Pseudorandom Number Generators
K. Kankaala, T. Ala-Nissila, I. Vattulainen
We present results of extensive bit level tests on some pseudorandom number generators which are commonly used in physics applications. The generators have first been tested with a…
