On the Convergence to the Non-equilibrium Steady State of a Langevin Dynamics with Widely Separated Time Scales and Different Temperatures
Nicolas Macris, Emanuele Mingione, Diego Alberici
We study the solution of the two-temperature Fokker-Planck equation and rigorously analyse its convergence towards an explicit non-equilibrium stationary measure for long time and two widely separated time scales. The exponential rates of convergence are e ...
Cham2024Twisting instabilities in elastic ribbons with inhomogeneous pre-stress: A macroscopic analog of thermodynamic phase transition
Pedro Miguel Nunes Pereira de Almeida Reis, Michael Christopher Gomez
We study elastic ribbons subject to large, tensile pre-stress confined to a central region within the cross-section. These ribbons can buckle spontaneously to form helical shapes, featuring regions of alternating chirality (phases) that are separated by so ...
PERGAMON-ELSEVIER SCIENCE LTD2023Controlling surface effects in extremely high aspect ratio gold plasmonic electrodes
Olivier Martin, Christian Santschi, Marco Riccardi
Nanofabrication is key to many technological advances, especially the challenge of merging nanophotonics with electronics. Here, we investigate the fabrication process of plasmonic interdigitated gold electrodes having a very high aspect ratio (i.e. long a ...
ELSEVIER2022Temperature- and pressure-dependence of the hydrogen bond network in plastic ice VII
Livia Eleonora Bove Kado, Umbertoluca Ranieri, Maria Rescigno
We model, via classical molecular dynamics simulations, the plastic phase of ice VII across a wide range of the phase diagram of interest for planetary investigations. Although structural and dynamical properties of plastic ice VII are mostly independent o ...
AIP Publishing2022Experimental Method to Distinguish between a Solution and a Suspension
Francesco Stellacci, Paulo Henrique Jacob Silva, Quy Ong Khac, Xufeng Xu, Ting Mao
Dispersion of objects in a fluid phase can be classified as solutions (Gibbs free energy of mixing, Delta G(mix) < 0) or suspensions (Delta G(mix) > 0) depending on their thermodynamic stability. Small objects tend to form solutions, larger ones suspension ...
WILEY2022Dissipation-driven selection of states in non-equilibrium chemical networks
Paolo De Los Rios, Daniel Maria Busiello, Shiling Liang, Francesco Piazza
Life has most likely originated as a consequence of processes taking place in non-equilibrium conditions (e.g. in the proximity of deep-sea thermal vents) selecting states of matter that would have been otherwise unfavorable at equilibrium. Here we present ...
2021Aggregation of discoidal particles due to depletion interaction
Depletion interactions between colloids of discoidal shape can induce their self-assembly into columnar aggregates. This is an effect of entropic origin with important implications in a range of colloidal systems, particularly in the clustering of erythroc ...
2021Characterising Structure and Stability of Materials using Machine Learning
The search of novel materials using in-silico high-throughput screening is emerging as a fundamental step in the pipeline of materials discovery, but its low yields in terms of synthesisable structures limit its effectiveness. In order to isolate configura ...
EPFL2020Self-Assembly of Microscopic Rods Due to Depletion Interaction
In this article, using numerical simulations we investigate the self-assembly of rod-like particles in suspension due to depletion forces which naturally emerge due to the presence of smaller spherical depletant particles. We characterize the type of clust ...
2020Membraneless organelles: phasing out of equilibrium
Over the past years, liquid-liquid phase separation (LLPS) has emerged as a ubiquitous principle of cellular organization implicated in many biological processes ranging from gene expression to cell division. The formation of biological condensates, like t ...
