On the existence of an intermediate phase in the antiferromagnetic Ising model on an face-centered cubic lattice
Graeme J Ackland
We use Monte Carlo simulation to determine the stable structures in the second-neighbour Ising model on the face-centred cubic lattice. Those structures are L1_1 for strongly antif…
Two state model for critical points and the negative slope of the melting-curve
Graeme J. Ackland, Hongxiang Zong, Victor Naden Robinson Sandro Scandolo +1
We present a thermodynamic model which explains the presence of a negative slope in the melt curve, as observed in systems as diverse as the alkali metals and molecular hydrogen at…
On the Diffusion of Sticky Particles in 1D
Joshua D M Hellier, Graeme J Ackland
The 1D Ising model is the simplest Hamiltonian-based model in statistical mechanics. The sim- plest interacting particle process is the Symmetric Exclusion Process (SEP), a 1D latt…
quasiharmonic equations of state for dynamically-stabilized soft-mode materials
N. D. Drummond, G. J. Ackland
We introduce a method for treating soft modes within the analytical framework of the quasiharmonic equation of state. The corresponding double-well energy-displacement relation is…
