Local vs. cooperative: Unraveling glass transition mechanisms with SEER
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 the temperature decreases, many events must occur in a coordinated fashion on a ...
Natl Acad Sciences2024Testing Theories of the Glass Transition with the Same Liquid but Many Kinetic Rules
Matthieu Wyart, Carolina Brito Carvalho dos Santos
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. Beyond the usual dynamics of liquids, this class includes dynamics in ...
Amer Physical Soc2024Reduced order modeling of parametrized pulsatile blood flows: Hematocrit percentage and heart rate
This paper numerically evaluates the accuracy and performance of a stabilized finite element Reduced Order Modelling (ROM) approach that is designed to simulate pulsatile blood flows. The method is able to estimate fluid flow parametric solutions of intere ...
PERGAMON-ELSEVIER SCIENCE LTD2023Fiber Buckling in Confined Viscous Flows: An Absolute Instability Described by the Linear Ginzburg-Landau Equation
François Gallaire, Jean Cappello
We explore the dynamics of a flexible fiber transported by a viscous flow in a Hele-Shaw cell of height comparable to the fiber height. We show that long fibers aligned with the flow experience a buckling instability. Competition between viscous and elasti ...
AMER PHYSICAL SOC2022Small-time global stabilization of the viscous Burgers equation with three scalar controls
We construct explicit time-varying feedback laws leading to the global (null) stabilization in small time of the viscous Burgers equation with three scalar controls. Our feedback laws use first the quadratic transport term to achieve the small-time global ...
2021Resin Transfer molding of High-Fluidity Polyamide-6 with modified Glass-Fabric preforms
Véronique Michaud, Damiano Salvatori, Baris Çaglar, Robin Samuel Trigueira, Colin Gomez
In Resin Transfer Molding (RTM), resin precursors of thermoset or, more recently, thermoplastic polymers are generally employed, raising issues related to the chemical reaction taking place during and after part processing. In this study, already polymeriz ...
2021Thermal origin of quasilocalized excitations in glasses
Matthieu Wyart, Thomas Willem Jan de Geus, Elisabeth Agoritsas, Wencheng Ji, Marko Popovic
Key aspects of glasses are controlled by the presence of excitations in which a group of particles can rearrange. Surprisingly, recent observations indicate that their density is dramatically reduced and their size decreases as the temperature of the super ...
AMER PHYSICAL SOC2020Strategies for faster impregnation in melt thermoplastic resin transfer molding process
Continuous fiber thermoplastic composites are potential substitutes of steel in structural automotive components, since they combine fiber strength and rigidity with ductility, potential recyclability and low density of the thermoplastic (TP) matrix. Resin ...
EPFL2018Energy Dissipation in Suspended Microchannel Resonators: theoretical, numerical and experimental validation
Suspended Microchannel Resonators (SMRs) are hollow resonant structures containing an embedded U-shaped microfluidic channel. Theoretical and experimental results have proved that in these devices the energy dissipation is a non-monotonic function of the f ...
2018From rock to magma and back again: The evolution of temperature and deformation mechanism in conduit margin zones
Marie Estelle Solange Violay, Michael Heap
Explosive silicic volcanism is driven by gas overpressure in systems that are inefficient at outgassing. The zone at the margin of a volcanic conduit-thought to play an important role in the outgassing of magma and therefore pore pressure changes and explo ...
