Brownian dynamics with soft constraints in soft matter systems
Sophie Marbach, Adam Carter, Miranda Holmes-Cerfon
Stiff forces, which bind objects together or otherwise confine motion, are found widely in soft-matter systems -- colloids with short range attractions, ligand-receptor contacts, p…
The Countoscope for self-propelled particles
Tristan Cerdin, Talia Calazans, Carine Douarche +1
Particle number fluctuations , measured in virtual observation boxes of an image or a simulation, offer a way to quantify particle dynamics when particle tracking is impracti…
Number fluctuations distinguish different self-propelling dynamics
Tristan Cerdin, Sophie Marbach, Carine Douarche
In nonequilibrium suspensions, static number fluctuations in virtual observation boxes reveal remarkable structural properties, but the dynamic potential of signals rema…
The "Intensity" Countoscope: Measuring particle dynamics in real space from microscopy images
Sophie Hermann, Seyed Saman Banarooei, Adam Carter +2
Advances in intensity-based microscopy techniques have improved our ability to quantify particle motion at microscopic scales, enabling insight into diffusion and collective dynami…
How adaptation to food resources and death rates shape oscillatory dynamics in a microbial population
Benedetta Ciarmoli, Sophie Marbach
Microbes constantly interact with their environment by depleting and transforming food sources. Theoretical studies have mainly focused on Lotka-Volterra models, which do not accou…
Collective Hard Core Interactions Leave Multiscale Signatures in Number Fluctuation Spectra
Eleanor K. R. Mackay, Anna Drummond Young, Adam Carter +2
A full understanding of transport in dense, interacting suspensions requires analysis frameworks sensitive to self and collective dynamics across all relevant spatial and temporal…
