Critical point calculation for binary mixtures of symmetric non-additive hard disks

Critical point calculation for binary mixtures of symmetric non-additive hard disks

We have calculated the values of critical packing fractions for the mixtures of symmetric non-additive 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...
