Critical point of liquid-gas (LG) transition does not conform with the paradigm of spontaneous symmetry breaking because there is no broken symmetry in both phases. We revisit the conjecture that this critical point belongs to the Ising class by performing large scale Monte Carlo simulations in two-dimensional free space in combination with the numerical flowgram method. Our main result is that the critical indices do agree with the Onsager values within the error of 1%-2%. This significantly…

It is demonstrated here that a generic critical MIPS belongs to the Ising universality class with conservative dynamics, by showing that a universal MIPS at criticality belongs to that class.

Monte Carlo simulations within the grand canonical ensemble are used to explore the liquid-vapour coexistence curve and critical point properties of the Lennard-Jones fluid and it is demonstrated that this procedure permits an efficient and accurate mapping of the coexistence Curve, even deep within the two phase region.
