Property-dependent material times
Aude Y. Amari, Lorenzo Costigliola, Jeppe C. Dyre
We analyze simulations of physical aging following large temperature up-jumps from equilibrated, slowly relaxing states. Specifically, we consider up-jumps from temperatures T=0.43…
Large temperature-up-jump simulations of a binary Lennard-Jones system
Aude Y. Amari, Lorenzo Costigliola, Jeppe C. Dyre
This paper presents simulations of the physical aging of a binary Kob-Andersen-type Lennard-Jones liquid following large temperature up-jumps from equilibrated states of high relax…
Swap Monte Carlo for diatomic molecules
Till Böhmer, Jeppe C. Dyre, Lorenzo Costigliola
In recent years the Swap Monte Carlo algorithm has led to remarkable progress in equilibrating supercooled model liquids at low temperatures. Applications have so far been limited…
Interpolating between pair-potential systems
Lorenzo Costigliola, Andreas C. Martine, Claudia X. Romero +4
This paper studies liquid-model systems with almost identical constant-potential-energy hypersurfaces. We simulated continuous interpolations between such systems, specifically bet…
view on energy polydisperse Lennard-Jones systems
Danqi Lang, Lorenzo Costigliola, Jeppe C. Dyre
When energy polydispersity is introduced into the Lennard-Jones (LJ) system, there is little effect on structure and dynamics [Ingebrigtsen and Dyre, J. Phys. Chem. B 127, 2837 (20…
Freezing, melting and the onset of glassiness in binary mixtures
Daniele Coslovich, Leonardo Galliano, Lorenzo Costigliola
We clarify the relationship between freezing, melting, and the onset of glassy dynamics in a prototypical glass-forming mixture model. Our starting point is a precise operational d…
