The RFOT theory of glasses: Recent progress and open issues

G Biroli, JP Bouchaud - Comptes …, 2023 - comptes-rendus.academie-sciences …
The Random First Order Transition (RFOT) theory started with the pioneering work of
Kirkpatrick, Thirumalai and Wolynes. It leverages methods and advances of the theory of …

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 …

Jammed solids with pins: Thresholds, force networks, and elasticity

AL Zhang, SA Ridout, C Parts, A Sachdeva, CS Bester… - Physical Review E, 2022 - APS
The role of fixed degrees of freedom in soft or granular matter systems has broad
applicability and theoretical interest. Here we address questions of the geometrical role that …

Block analysis for the calculation of dynamic and static length scales in glass-forming liquids

S Chakrabarty, I Tah, S Karmakar, C Dasgupta - Physical Review Letters, 2017 - APS
We present block analysis, an efficient method of performing finite-size scaling for obtaining
the length scale of dynamic heterogeneity and the point-to-set length scale for generic glass …

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 …

Athermal quasistatic cavitation in amorphous solids: Effect of random pinning

UA Dattani, S Karmakar, P Chaudhuri - The Journal of Chemical …, 2023 - pubs.aip.org
Amorphous solids are known to fail catastrophically via fracture, and cavitation at nano-
metric scales is known to play a significant role in such a failure process. Micro-alloying via …

Effect of pinning on the yielding transition of amorphous solids

BP Bhowmik, P Chaudhuri, S Karmakar - Physical review letters, 2019 - APS
Using numerical simulations, we have studied the yielding response, in the athermal
quasistatic limit, of a model amorphous material having inclusions in the form of randomly …

Effects of random pinning on the potential energy landscape of a supercooled liquid

SP Niblett, VK De Souza, RL Jack… - The Journal of chemical …, 2018 - pubs.aip.org
We use energy landscape methods to investigate the response of a supercooled liquid to
random pinning. We classify the structural similarity of different energy minima using a …

Probing dynamic heterogeneity and amorphous order using rotational dynamics of rodlike particles in supercooled liquids

A Mutneja, S Karmakar - Physical Review Applied, 2021 - APS
Probing dynamic and static correlations in glass-forming supercooled liquids has been a
challenge for decades despite extensive research. Dynamic correlation, which manifests …

Particle pinning suppresses spinodal criticality in the shear-banding instability

BP Bhowmik, S Karmakar, I Procaccia, C Rainone - Physical Review E, 2019 - APS
Strained amorphous solids often fail mechanically by creating a shear band. It had been
understood that the shear-banding instability is usefully described as crossing a spinodal …
