Nucleation simulation using a model of hard/soft discs

Milanović, Željka; Pivac, Branko; Zulim, Ivan - In: Physica A: Statistical Mechanics and its Applications 417 (2015) C, pp. 86-95

In this paper we present a computer study of the quantum dot (QD) nucleation probability with three possible models of particle interaction; Soft Core (SC), Hard Core (HC) and Hard Core/Soft Shell (HCSS) model. Computer analysis of the nucleation probability is performed on a 500 by 500 lattice...

The approximate invariance of the average number of connections for the continuum percolation of squares at criticality

Sreenivasan, Sameet; Baker, Don R.; Paul, Gerald; … - In: Physica A: Statistical Mechanics and its Applications 320 (2003) C, pp. 34-40

We perform Monte Carlo simulations to determine the average excluded area 〈Aex〉 of randomly oriented squares, randomly oriented widthless sticks and aligned squares in two dimensions. We find significant differences between our results for randomly oriented squares and previous analytical...

Continuum percolation of simple fluids: energetic connectivity criteria

Pugnaloni, Luis A; Márquez, Ileana F; Vericat, Fernando - In: Physica A: Statistical Mechanics and its Applications 321 (2003) 3, pp. 398-410

During the last few years, a number of works in computer simulation have focused on the clustering and percolation properties of simple fluids based on an energetic connectivity criterion proposed long ago by T.L. Hill (J. Chem. Phys. 23 (1955) 617). This connectivity criterion appears to be the...
