15 Aug 2019 | | Abstract: | The determination of phase behavior and, in particular, the nature of phase
transitions in two-dimensional systems is often clouded by finite size effects
and by access to the appropriate thermodynamic regime. We address these issues
using an alternative route to deriving the equation of state of a
two-dimensional hard-core particle system, based on kinetic arguments and the
Gibbs adsorption isotherm, by use of the random sequential adsorption with
surface diffusion (RSAD) model. Insight into coexistence regions and phase
transitions is obtained through direct visualization of the system at any
fractional surface coverage via local bond orientation order. The analysis of
the bond orientation correlation function for each individual configuration
confirms that first-order phase transition occurs in a two-step
liquid-hexatic-solid transition at high surface coverage. | | Source: | arXiv, 1908.5555 | | Services: | Forum | Review | PDF | Favorites | |
