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 MartÃn-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…
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…
Tangentially Active Polymers in Cylindrical Channels
José MartÃn-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…
