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…
