Internal stress drives ferromagnetic-like ordering in networks of proliferating bacteria
Nicola Pellicciotta, Luca Angelani, Roberto Di Leonardo
Proliferation is a defining feature of life. Through growth, division, and death, living systems consume energy and inject mass, breaking conservation laws and driving collective p…
Fluidization induced by Magnetic Interactions in Confined Active Matter
Marco Musacchio, Markus Felber, Matteo Paoluzzi +3
We investigate magnetic active matter in confined geometries using both experiments with magnetic toy robots Hexbugs and simulations of elongated magnetic active Brownian particles…
Local entropy production rate of run-and-tumble particles
Matteo Paoluzzi, Andrea Puglisi, Luca Angelani
We study the local entropy production rate and the local entropy flow in active systems composed of non-interacting run-and-tumble particles in a thermal bath. After providing gene…
Anomalous random flights and time-fractional run-and-tumble equations
Luca Angelani, Alessandro De Gregorio, Roberto Garra +1
Random flights (also called run-and-tumble walks or transport processes) represent finite velocity random motions changing direction at any Poissonian time. These models in d-dimen…
Generalized time-fractional kinetic-type equations with multiple parameters
Luca Angelani, Alessandro De Gregorio, Roberto Garra
In this paper we study a new generalization of the kinetic equation emerging in run-and-tumble models. We show that this generalization leads to a wide class of generalized fractio…
Entropy production of run-and-tumble particles
Matteo Paoluzzi, Andrea Puglisi, Luca Angelani
We analyze the entropy production in run-and-tumble models. After presenting the general formalism in the framework of the Fokker-Planck equations in one space dimension, we derive…
