"Swarm relaxation": Equilibrating a large ensemble of computer simulations
Shahrazad M. A. Malek, Richard K. Bowles, Ivan Saika-Voivod +2
It is common practice in molecular dynamics and Monte Carlo computer simulations to run multiple, separately-initialized simulations in order to improve the sampling of independent…
Thermal ratchet effect in confining geometries
Viktor Holubec, Artem Ryabov, Mohammad Hassan Yaghoubi +4
Stochastic model of the Feynman-Smoluchowski ratchet is proposed and solved using generalization of the Fick-Jacobs theory. The theory fully captures nonlinear response of the ratc…
The critical pulling force for self-avoiding walks
Nicholas R. Beaton
Self-avoiding walks are a simple and well-known model of long, flexible polymers in a good solvent. Polymers being pulled away from a surface by an external agent can be modelled w…
Free energy surface of ST2 water near the liquid-liquid phase transition
Peter H. Poole, Richard K. Bowles, Ivan Saika-Voivod +1
We carry out umbrella sampling Monte Carlo simulations to evaluate the free energy surface of the ST2 model of water as a function two order parameters, the density and a bond-orie…
Heterogeneous Nucleation in the Low Barrier Regime
Benjamin Scheifele, Ivan Saika-Voivod, Richard K. Bowles +1
In simulations of the 2D Ising model, we examine heterogeneous nucleation induced by a small impurity consisting of a line of fixed spins. As increases, we identify a limit…
Gaussian approximation to single particle correlations at and below the picosecond scale for Lennard-Jones and nanoparticle fluids
R. van Zon, S. S. Ashwin, E. G. D. Cohen
To describe short-time (picosecond) and small-scale (nanometre) transport in fluids, a Green's function approach was recently developed. This approach relies on an expansion of the…
