Curvature-induced host-mediated polarization of active particles
Giulia Janzen, D. A. Matoz-Fernandez
Polar collective motion commonly arises from alignment interactions, particle anisotropy, or an imposed directional bias. Here we identify a distinct route to polar order that does…
Persistence-Driven Void Formation in Dense Active-Passive Mixtures
Giulia Janzen, Liesbeth M. C. Janssen, Nuno A. M. Araújo +2
It is well established that dilute active dopants can melt an arrested amorphous solid by enhancing cage breaking and accelerating structural relaxation. Yet it remains unclear whe…
Active Matter as a framework for living systems-inspired Robophysics
Giulia Janzen, Gaia Maselli, Juan F. Jimenez +3
Robophysics investigates the physical principles that govern living-like robots operating in complex, realworld environments. Despite remarkable technological advances, robots cont…
Active Filaments on Curved Surfaces: From Single Filaments to Dilute Suspensions
Giulia Janzen, Euan D. Mackay, Rastko Sknepnek +1
Curvature plays a central organizational role in active polymer dynamics. Using large-scale Langevin-dynamics simulations, we study active semiflexible filaments confined to smooth…
Collective filament wrapping and nested spiral formation in active polydisperse systems
Caterina Landi, Giulia Janzen, Francesco Sciortino +3
We investigate a two-dimensional polydisperse suspension of self-propelled semiflexible filaments and reveal a collective wrapping mechanism that is absent in monodisperse systems.…
Emergent Dynamics of Active Systems on Curved Environments
Euan D. Mackay, Giulia Janzen, D. A. Matoz Fernandez +1
Curvature plays a central role in the proper function of many biological processes. With active matter being a standard framework for understanding many aspects of the physics of l…
Active Polymer Behavior in Two Dimensions: A Comparative Analysis of Tangential and Push-Pull Models
Giulia Janzen, Juan Pablo Miranda, José Martín-Roca +4
In this work, we compare the structural and dynamic behavior of active filaments in two dimensions using tangential and push-pull models, including a variant with passive end monom…
Density and inertia effects on two-dimensional active semiflexible filament suspensions
Giulia Janzen, D. A. Matoz-Fernandez
We examine the influence of density on the transition between chain and spiral structures in planar assemblies of active semiflexible filaments, utilizing detailed numerical simula…
