How Spatially Modulated Activity Reshapes Active Polymer Conformations
Paolo Malgaretti, Emanuele Locatelli
Active polymers are driven out of equilibrium by internal forces and exhibit conformational properties that differ fundamentally from those of passive chains. Here we study how spa…
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…
Tangentially Active Polymers in Cylindrical Channels
José Martín-Roca, Emanuele Locatelli, Valentino Bianco +2
We present an analytical and computational study characterizing the structural and dynamical properties of an active filament confined in cylindrical channels. We first outline the…
Coil-to-globule collapse of active polymers: a Rouse perspective
P. Malgaretti, E. Locatelli, C. Valeriani
We derive an effective Rouse model for tangentially active polymers, characterized by a constant active force tangent to their backbone. In particular, we show that, once extended…
Non-monotonous translocation time of polymers across pores
Emanuele Locatelli, Valentino Bianco, Chantal Valeriani +1
Polymers confined in corrugated channels, i.e. channels of varying amplitude, display {multiple local maxima and minima of the diffusion coefficient upon increasing their degree of…
Globule-like conformation and enhanced diffusion of active polymers
Valentino Bianco, Emanuele Locatelli, Paolo Malgaretti
We study the dynamics and conformation of polymers composed by active monomers. By means of Brownian dynamics simulations we show that when the direction of the self-propulsion of…
Non-monotonous polymer translocation time across corrugated channels: comparison between Fick-Jacobs approximation and numerical simulations
Valentino Bianco, Paolo Malgaretti
We study the translocation of polymers across varying-section channels. Using systematic approximations, we derive a simplified model that reduces the problem of polymer translocat…
