Efficient tight-binding Monte Carlo structural sampling of complex materials
Parthapratim Biswas, G. T. Barkema, Normand Mousseau +1
While recent work towards the development of tight-binding and ab-initio algorithms has focused on molecular dynamics, Monte Carlo methods can often lead to better results with rel…
Equilibrium crystal shapes in the Potts model
R. P. Bikker, G. T. Barkema, H. van Beijeren
The three-dimensional -state Potts model, forced into coexistence by fixing the density of one state, is studied for , 3, 4, and 6. As a function of temperature and number…
Symmetry effects and equivalences in lattice models of hydrophobic interaction
G. M. Schütz, I. Ispolatov, G. T. Barkema +1
We establish the equivalence of a recently introduced discrete model of the hydrophobic interaction, as well as its extension to continuous state variables, with the Ising model in…
Relation between Raman spectra and Structure of Amorphous Silicon
R. L. C. Vink, G. T. Barkema, W. F. van der Weg
In 1985, Beeman, Tsu and Thorpe established an almost linear relation between the Raman transverse-optic (TO) peak width and the spread in mean bond angle in a-Si. This relation is…
A cluster algorithm for Potts models with fixed spin densities
R. P. Bikker, G. T. Barkema
A cluster algorithm is presented for the simulation of the q-state Potts models in which the number of spins is conserved in each state. The algorithm constructs Fortuin-Kasteleyn…
Model of Hydrophobic Attraction in Two and Three Dimensions
G. T. Barkema, B. Widom
An earlier one-dimensional lattice model of hydrophobic attraction is extended to two and three dimensions and studied by Monte Carlo simulation. The solvent-mediated contribution…
