Soft-wall induced structure and dynamics of partially confined supercritical fluids [PDF]
J. Chem. Phys. 150, 111102 (2019), 2019 The interplay between the structure and dynamics of partially confined Lennard Jones (LJ) fluids, deep into the supercritical phase, is studied over a wide range of densities in the context of the Frenkel line (FL), which separates rigid liquidlike and non-rigid gaslike regimes in the phase diagram of the supercritical fluids.
