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…
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…
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…
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…
Complexity Scaling of Liquid Dynamics
Ian M. Douglass, Jeppe C. Dyre, Lorenzo Costigliola
According to excess-entropy scaling, dynamic properties of liquids like viscosity and diffusion coefficient are determined by the entropy. This link between dynamics and thermodyna…
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…
Time reversibility during the ageing of materials
Till Böhmer, Jan P. Gabriel, Lorenzo Costigliola +4
Physical ageing is the generic term for irreversible processes in glassy materials resulting from molecular rearrangements. One formalism for describing such ageing processes invol…
Active-parameter polydispersity in the 2d ABP Yukawa model
Shibu Saw, Lorenzo Costigliola, Jeppe C. Dyre
In both experiments and simulations the most commonly studied kind of parameter polydispersity is that of varying particles size. This paper investigates by simulations the effects…
Active-matter isomorphs in the size-polydisperse Ornstein-Uhlenbeck Lennard-Jones model
Daniel Jespersen, Lorenzo Costigliola, Jeppe C. Dyre +1
This paper studies size-polydisperse Lennard-Jones systems described by active Ornstein-Uhlenbeck particle dynamics. The focus is on the existence of isomorphs (curves of invariant…
Configurational temperature in active matter. II. Quantifying the deviation from thermal equilibrium
Shibu Saw, Lorenzo Costigliola, Jeppe C. Dyre
This paper suggests using the configurational temperature $\Tc$ for quantifying how far an active-matter system is from thermal equilibrium. We measure this ``distance'' by the rat…
Single-parameter aging in the weakly nonlinear limit
Saeed Mehri, Lorenzo Costigliola, Jeppe C. Dyre
Physical aging deals with slow property changes over time caused by molecular rearrangements. This is relevant for non-crystalline materials like polymers and inorganic glasses, bo…
A toy model for viscous liquid dynamics
Filip Samuelsen, Lorenzo Costigliola, Thomas B. Schrøder
A simple model for viscous liquid dynamics is introduced. Consider the surface of the union of hyper-spheres centered at random positions inside a hypercube with periodic boundary…
Connecting Entropy Scaling and Density Scaling
Ian Bell, Robin Fingerhut, Jadran Vrabec +1
It is shown that the residual entropy (entropy minus that of the ideal gas at the same temperature and density) is mostly synonymous with the independent variable of density scalin…
Configurational temperature in active matter. I. Lines of invariant physics in the phase diagram of the Ornstein-Uhlenbeck model
Shibu Saw, Lorenzo Costigliola, Jeppe C. Dyre
This paper shows that the configurational temperature of liquid-state theory, $\Tc$, defines an energy scale, which can be used for adjusting model parameters of active Ornstein-Uh…
Density scaling of generalized Lennard-Jones fluids in different dimensions
Thibaud Maimbourg, Jeppe C. Dyre, Lorenzo Costigliola
Liquids displaying strong virial-potential energy correlations conform to an approximate density scaling of their structural and dynamical observables. This scaling property does n…
Density-scaling exponents and virial potential-energy correlation coefficients for the (2n,n) Lennard-Jones system

The recent theoretical prediction by Maimbourg and Kurchan [arXiv:1603.05023] that for regular pair-potential systems the virial potential-energy correlation coefficient increases…
Freezing and melting line invariants of the Lennard-Jones system
Lorenzo Costigliola, Thomas B. Schrøder, Jeppe C. Dyre
The invariance of several structural and dynamical properties of the Lennard-Jones (LJ) system along the freezing and melting lines is interpreted in terms of the isomorph theory.…
