Crossover from gas-like to liquid-like molecular diffusion in a simple supercritical fluid
According to textbooks, no physical observable can be discerned allowing to distinguish a
liquid from a gas beyond the critical point. Yet, several proposals have been put forward …

Topological generalization of the rigid-nonrigid transition in soft-sphere and hard-sphere fluids
A fluid particle changes its dynamics from diffusive to oscillatory as the system density
increases up to the melting density. Hence the notion of the Frenkel line was introduced to …
