Solid-that-Flows Picture of Glass-Forming Liquids

JC Dyre - The Journal of Physical Chemistry Letters, 2024 - ACS Publications
This perspective article reviews arguments that glass-forming liquids are different from those
of standard liquid-state theory, which typically have a viscosity in the mPa· s range and …

Emergent facilitation and glassy dynamics in supercooled liquids

MR Hasyim, KK Mandadapu - Proceedings of the National …, 2024 - National Acad Sciences
In supercooled liquids, dynamical facilitation refers to a phenomenon where microscopic
motion begets further motion nearby, resulting in spatially heterogeneous dynamics. This is …

Testing Theories of the Glass Transition with the Same Liquid but Many Kinetic Rules

C Gavazzoni, C Brito, M Wyart - Physical Review Letters, 2024 - APS
We study the glass transition by exploring a broad class of kinetic rules that can significantly
modify the normal dynamics of supercooled liquids while maintaining thermal equilibrium …

Logarithmic aging via instability cascades in disordered systems

D Shohat, Y Friedman, Y Lahini - Nature Physics, 2023 - nature.com
Many complex and disordered systems fail to reach equilibrium after they have been
quenched or perturbed. Instead, they sluggishly relax toward equilibrium at an ever-slowing …

Direct numerical analysis of dynamic facilitation in glass-forming liquids

C Herrero, L Berthier - Physical Review Letters, 2024 - APS
We propose a computational strategy to quantify the temperature evolution of the timescales
and length scales over which dynamic facilitation affects the relaxation dynamics of glass …

Local vs. cooperative: Unraveling glass transition mechanisms with SEER

M Pica Ciamarra, W Ji, M Wyart - Proceedings of the …, 2024 - National Acad Sciences
Which phenomenon slows down the dynamics in supercooled liquids and turns them into
glasses is a long-standing question of condensed matter. Most popular theories posit that as …

Soft pinning: Experimental validation of static correlations in supercooled molecular glass-forming liquids

R Das, BP Bhowmik, AB Puthirath, TN Narayanan… - PNAS …, 2023 - academic.oup.com
Enormous enhancement in the viscosity of a liquid near its glass transition is a hallmark of
glass transition. Within a class of theoretical frameworks, it is connected to growing many …

Glass-forming liquids need facilitation

L Costigliola, T Hecksher… - Proceedings of the …, 2024 - National Acad Sciences
Fig. 1. Imaginary parts of dynamic linear-response functions of glass-forming liquids of
different chemistry scaled to maximum loss and loss-peak frequency. Orange full curves and …

Why is the dynamics of glasses super-Arrhenius?

JP Bouchaud - arXiv preprint arXiv:2402.01883, 2024 - arxiv.org
The steep increase of the relaxation time of glass forming liquids upon cooling is traditionally
ascribed to an impending entropy crisis: since the system has" nowhere to go", dynamics …

Earthquakelike dynamics in ultrathin magnetic films

G Durin, VM Schimmenti, M Baiesi, A Casiraghi… - Physical Review B, 2024 - APS
We study the motion of a domain wall on an ultrathin magnetic film using the magneto-
optical Kerr effect (MOKE). Our measurements were conducted at magnetic fields …
