Multiscale perturbative approach to active matter with motility regulation
Alberto Dinelli, Pietro Luigi Muzzeddu
We present a coarse-graining method applicable to dry scalar active matter with motility regulation. Our approach, based on a multiscale perturbative expansion of the backward Kolm…
Unifying hydrodynamic theory for motility-regulated active matter: from single particles to interacting polymers
Alberto Dinelli, Pietro Luigi Muzzeddu
Understanding how microscopic motility shapes emergent collective behaviors is a challenging task in active matter, especially when self-propulsion is regulated by external cues or…
Structure and dynamics of a Rouse polymer in a fluctuating correlated medium
Pietro Luigi Muzzeddu, Davide Venturelli, Andrea Gambassi
We study the static and dynamical properties of a harmonically confined Rouse polymer coupled to a fluctuating correlated medium, which affect each other reciprocally during their…
Transport of molecules via polymerization in chemical gradients
Shashank Ravichandir, Bhavesh Valecha, Pietro Luigi Muzzeddu +2
The transport of molecules for chemical reactions is critically important in various cellular biological processes. Despite thermal diffusion being prevalent in many biochemical pr…
Active Transport of Cargo-Carrying and Interconnected Chiral Particles
Bhavesh Valecha, Hossein Vahid, Pietro Luigi Muzzeddu +2
Directed motion up a concentration gradient is crucial for the survival and maintenance of numerous biological systems, such as sperms moving towards an egg during fertilization or…
Migration and separation of polymers in non-uniform active baths
Pietro Luigi Muzzeddu, Andrea Gambassi, Jens-Uwe Sommer +1
Polymer-like structures are ubiquitous in nature and synthetic materials. Their configurational and migration properties are often affected by crowded environments leading to non-t…
Taxis of cargo-carrying microswimmers in traveling activity waves
Pietro Luigi Muzzeddu, Édgar Roldán, Andrea Gambassi +1
Many fascinating properties of biological active matter crucially depend on the capacity of constituting entities to perform directed motion, e.g., molecular motors transporting ve…
Active chiral molecules in activity gradients
Pietro Luigi Muzzeddu, Hidde Derk Vuijk, Hartmut Lowen +2
While the behavior of active colloidal molecules is well studied by now for a constant activity, the effect of activity gradients is much less understood. Here we explore one of th…
