It is now 100 years since Lennard-Jones published his first paper introducing the now
famous potential that bears his name. It is therefore timely to reflect on the many …

Water is the most abundant liquid on earth and also the substance with the largest number
of anomalies in its properties. It is a prerequisite for life and as such a most important subject …

A vibrational model of transport properties of dense fluids assumes that solid-like oscillations
of atoms around their temporary equilibrium positions dominate the dynamical picture. The …

Strongly interacting, dynamically disordered and with no small parameter, liquids took a
theoretical status between gases and solids with the historical tradition of hydrodynamic …

It is generally agreed that the supercritical region of a liquid consists of one single state
(supercritical fluid). On the other hand, we show here that liquids in this region exist in two …

Experimental, computational, and theoretical results have shown that the notion of a
homogeneous supercritical state space has to be replaced with distinct liquid-like and gas …

A large and mostly unexplored part of the phase diagram lies above the critical point. The
supercritical matter was traditionally believed to be physically homogeneous with no …

Of the three basic states of matter, liquid is perhaps the most complex. While its flow
properties are described by fluid mechanics, its thermodynamic properties are often …

Supercritical water is fundamental in many fields of applications and a precise
characterization of the supercritical state is of uttermost importance for this liquid. In a fluid …

We discuss the fluid state of matter at high temperature and pressure. We review the existing
ways in which the boundary between a liquid and a quasigas fluid above the critical point …
