We have calculated the values of critical packing fractions for the mixtures of symmetric nonadditive hard disks.
An interesting feature of the model is the fact that the internal energy is zero and the phase transitions are entropically driven.
A cluster algorithm for Monte Carlo simulations in a semigrand ensemble was used. The finite size scaling analysis was employed
to compute the critical packing fractions for infinite systems with high accuracy for a range of nonadditivity parameters wider
than in the previous studies.
Key words:
phase coexistence, critical point, finite size scaling, Monte Carlo simulations
