Universality, scaling and collapse in supercritical fluids
Min Young Ha, Tae Jun Yoon, Tsvi Tlusty +2
The Supercritical Fluid (SCF) is known to exhibit salient dynamic and thermodynamic crossovers and inhomogeneous molecular distribution. But the question as to what basic physics u…
Topological extension of the isomorph theory based on the Shannon entropy
Tae Jun Yoon, Min Young Ha, Emanuel A. Lazar +2
Isomorph theory is one of the promising theories to understand the quasi-universal relationship between thermodynamic, dynamic and structural characteristics. Based on the hidden s…
A corresponding-state framework for the structural transition of supercritical fluids across the Widom delta
Tae Jun Yoon, Min Young Ha, Won Bo Lee +1
This work proposes a classification algorithm based on the radical Voronoi tessellation to define the Widom delta, supercritical gas-liquid coexistence region, of polyatomic molecu…
Topological generalization of the rigid-nonrigid transition in soft-sphere and hard-sphere fluids
Tae Jun Yoon, Emanuel A. Lazar, Min Young Ha +2
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…
"Two-phase" thermodynamics of the Frenkel line
Tae Jun Yoon, Min Young Ha, Won Bo Lee +1
The Frenkel line, a crossover line between rigid and nonrigid dynamics of fluid particles, has recently been the subject of intense debate regarding its relevance as a partitioning…
Topological Characterization of Rigid-Nonrigid Transition across the Frenkel Line
Tae Jun Yoon, Min Young Ha, Emanuel A. Lazar +2
The dynamics of supercritical fluids, a state of matter beyond the gas-liquid critical point, changes from diffusive to oscillatory motions at high pressure. This transition is bel…
