A Limit of Stability in Supercooled Liquid Clusters
Eduardo Mendez-Villuendas Ivan Saika-Voivod Richard K. Bowles
We examine the metastable liquid phase of a supercooled gold nanocluster by studying the free energy landscape using the largest solid-like embryo as an order parameter. Just below…
Surface Nucleation in the Freezing of Gold Nanoparticles
Eduardo Mendez-Villuendas Richard K. Bowles
We use molecular simulation to calculate the nucleation free energy barrier for the freezing of a 456 atom gold cluster over a range of temperatures. The results show that the embr…
Test of classical nucleation theory on deeply supercooled high-pressure simulated silica
Ivan Saika-Voivod, Peter H. Poole, Richard K. Bowles
We test classical nucleation theory (CNT) in the case of simulations of deeply supercooled, high density liquid silica, as modelled by the BKS potential. We find that at density $ρ…
Landscapes, dynamic heterogeneity and kinetic facilitation in a simple off-lattice model
R. K. Bowles, I. Saika-Voivod
We present a simple off-lattice hard-disc model that exhibits glassy dynamics. The inherent structures are enumerated exactly, transitions between metabasins are well understood, a…
Osmotic force resisting chain insertion in a colloidal suspension
M. Castelnovo, R. K. Bowles, H. Reiss +1
We consider the problem of inserting a stiff chain into a colloidal suspension of particles that interact with it through excluded volume forces. The free energy of insertion is as…
