What is it about?
The interfacial tension, correlation length and specific heat of a binary mixture of immiscible fluids in two dimensions and quasi-two dimensions are shown to obey simple laws as functions of temperature, using mesoscale numerical simulations. These laws are characterized by universal exponents that depend only on dimensionality, not on the chemical composition of the fluids.

Why is it important?
We show for the first time that scaling laws that were known to work for strictly two-dimensional fluids, are valid also for quasi-two dimensional fluids. This is a nontrivial conclusion because experiments that test these scaling laws are never performed under strictly two-dimensional conditions.
Perspectives
This article is part of our group's efforts to show that quasi-two dimensional systems obey physical laws that are mathematically similar to those obeyed by their strictly two-dimensional counterparts.
