Transition in the supercritical state of matter: Review of experimental evidence

C Cockrell, VV Brazhkin, K Trachenko - Physics Reports, 2021 - Elsevier
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 …

Dynamic crossover in fluids: From hard spheres to molecules

IH Bell, S Delage-Santacreu, H Hoang… - The Journal of …, 2021 - ACS Publications
We propose a simple and generic definition of a demarcation reconciling structural and
dynamic frameworks when combined with the entropy scaling framework. This crossover …

Voronoi cell analysis: The shapes of particle systems

EA Lazar, J Lu, CH Rycroft - American Journal of Physics, 2022 - pubs.aip.org
Physical systems can often be abstracted as large sets of point-like objects in space, with
each point representing, for example, the position of an atom, colloidal particle, organism, or …

Atomistic structural mechanism for the glass transition: Entropic contribution

D Han, D Wei, J Yang, HL Li, MQ Jiang, YJ Wang… - Physical Review B, 2020 - APS
A popular Adam-Gibbs scenario has suggested that the excess entropy of glass and liquid
over crystal dominates the dynamical arrest at the glass transition with exclusive contribution …

Topological metric detects hidden order in disordered media

DJ Skinner, B Song, H Jeckel, E Jelli, K Drescher… - Physical Review Letters, 2021 - APS
Recent advances in microscopy techniques make it possible to study the growth, dynamics,
and response of complex biophysical systems at single-cell resolution, from bacterial …

Extreme case of density scaling: The Weeks-Chandler-Andersen system at low temperatures

E Attia, JC Dyre, UR Pedersen - Physical Review E, 2021 - APS
This paper studies numerically the Weeks-Chandler-Andersen system, which is shown to
obey hidden scale invariance with a density-scaling exponent that varies from below 5 to …

Thermodynamics, dynamics, and structure of supercritical water at extreme conditions

TJ Yoon, LA Patel, T Ju, MJ Vigil… - Physical Chemistry …, 2020 - pubs.rsc.org
Molecular dynamics (MD) simulations to understand the thermodynamic, dynamic, and
structural changes in supercritical water across the Frenkel line and the melting line have …

Isomorph theory beyond thermal equilibrium

JC Dyre - The Journal of Chemical Physics, 2020 - pubs.aip.org
This paper generalizes isomorph theory to systems that are not in thermal equilibrium. The
systems are assumed to be R-simple, ie, to have a potential energy that as a function of all …

Linking excess entropy and acentric factor in spherical fluids

TJ Yoon, IH Bell - The Journal of Chemical Physics, 2024 - pubs.aip.org
Introduced by Pitzer in 1955, the acentric factor (ω) has been used to evaluate a molecule's
deviation from the corresponding state principle. Pitzer devised ω based on a concept called …

Excess entropy scaling law: A potential energy landscape view

A Saliou, P Jarry, N Jakse - Physical Review E, 2021 - APS
The relationship between excess entropy and diffusion is revisited by means of large-scale
computer simulation combined to supervised learning approach to determine the excess …
