Sažetak
Aqueous mixtures of small solute molecules are characterized by a strong micro-heterogeneity. This micro-heterogeneity is distinct from concentration fluctuations, and can be characterised as the analog of the Lifshitz state well known in condensed matter and high energy physics. It corresponds to a state where "particles" can emerge from a fluctuating background. The difficulty of distinguishing the two manifestations has plagued the computer simulations of aqueous mixtures over two decades, in particular in determining the nature of the long range part of the correlations in finite size simulations. By using a mode mixture of water and "weak-water", where we scale down the partial charges of the oxygen and hydrogen sites, we obtain various models of molecular emulsions, analogous to realistic binary aqueous mixtures in many ways, and that allows us to illustrate how fluctuations and micro-heterogeneity manifest themselves into the structural and thermodynamical quantities.
