Problems with Chinchilla Approach 2: Systematic Biases in IsoFLOP Parabola Fits
Eric Czech, Zhiwei Xu, Yael Elmatad +2
Chinchilla Approach 2 is among the most widely used methods for fitting neural scaling laws. Its parabolic approximation introduces systematic biases in compute-optimal allocation…
Space-time phase transitions in the East model with a softened kinetic constraint
Yael S. Elmatad, Robert L. Jack
The East model has a dynamical phase transition between an active (fluid) and inactive (glass) state. We show that this phase transition generalizes to "softened" systems where con…
Manifestations of Dynamical Facilitation in Glassy Materials
Yael S. Elmatad, Aaron S. Keys
By characterizing the dynamics of idealized lattice models with a tunable kinetic constraint, we explore the different ways in which dynamical facilitation manifests itself within…
Fragile-to-Strong Crossover in Supercooled Liquids Remains Elusive
Yael S. Elmatad
A critique of a recent paper [Mallamace et al PNAS 2010 107 (52) 22457-2246] purporting the existence of a fragile-to-strong crossover in super cooled liquids is presented. It is s…
Corresponding States of Structural Glass Formers. II
Yael S. Elmatad, David Chandler, Juan P. Garrahan
The earlier paper of this same title demonstrated a collapse of relaxation data of fragile supercooled glass forming liquids [\textit{J. Phys. Chem. B} \textbf{113}, 5563-5567 (200…
Finite-temperature critical point of a glass transition
Yael S. Elmatad, Robert L. Jack, Juan P. Garrahan +1
We generalize the simplest kinetically constrained model of a glass-forming liquid by softening kinetic constraints, allowing them to be violated with a small finite rate. We demon…
Corresponding States of Structural Glass Formers
Yael S. Elmatad, David Chandler, Juan P. Garrahan
The variation with respect to temperature T of transport properties of 58 fragile structural glass forming liquids (68 data sets in total) are analyzed and shown to exhibit a remar…
