Accelerated dynamics with the dynamical activation-relaxation technique
G. T. Barkema, Normand Mousseau
The dynamics of many atomic systems is controlled by activated events taking place on a time scale which is long compared to that associated with thermal vibrations. This often pla…

Efficient sampling in complex materials at finite temperature: the thermodynamically-weighted activation-relaxation technique
Normand Mousseau, G. T. Barkema
We present an accelerated algorithm that samples correctly the thermodynamic ensemble in complex systems where the dynamics is controlled by activation barriers. The efficiency of…

Nucleation times in the 2D Ising model
K. Brendel, G. T. Barkema, H. van Beijeren
A theoretical framework is presented for the estimation of nucleation times in systems with Brownian type dynamics. This framework is applied to a prototype system: the two-dimensi…
