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…
Optimal escapes in active matter
Luca Angelani
The out-of-equilibrium character of active particles, responsible for accumulation at boundaries in confining domains, determines not-trivial effects when considering escape proces…
Alignment interactions drive structural transitions in biological tissues
Matteo Paoluzzi, Luca Angelani, Giorgio Gosti +3
Experimental evidence shows that there is a feedback between cell shape and cell motion. How this feedback impacts the collective behavior of dense cell monolayers remains an open…
Spontaneous assembly of colloidal vesicles driven by active swimmers
Luca Angelani
We explore the self-assembly process of colloidal structures immersed in active baths. By considering low-valence particles we numerically investigate the irreversible aggregation…
Currents and flux-inversion in photokinetic active particles
Claudio Maggi, Luca Angelani, Giacomo Frangipane +1
Many active particles, both of biological and synthetic origin, can have a light controllable propulsion speed, a property that in biology is commonly referred to as photokinesis.…
Self-Sustained Density Oscillations of Swimming Bacteria Confined in Microchambers
M. Paoluzzi, R. Di Leonardo, L. Angelani
We numerically study the dynamics of run-and-tumble particles confined in two chambers connected by thin channels. Two dominant dynamical behaviors emerge: (i) an oscillatory pumpi…
Generalized energy equipartition in harmonic oscillators driven by active baths
Claudio Maggi, Matteo Paoluzzi, Nicola Pellicciotta +3
We study experimentally and numerically the dynamics of colloidal beads confined by a harmonic potential in a bath of swimming E. coli bacteria. The resulting dynamics is well appr…
Self-Starting Micromotors in a Bacterial Bath
Luca Angelani, Roberto Di Leonardo, Giancarlo Ruocco
Micromotors pushed by biological entities, like motile bacteria, constitute a fascinating way to convert chemical energy into mechanical work at the micrometer scale. Here we show,…
Diffusivity and configurational entropy maxima in short range attractive colloids
Luca Angelani, Giuseppe Foffi, Francesco Sciortino +1
We study tagged particle diffusion at large packing fractions, for a model of particles interacting with a generalized Lennard-Jones 2n-n potential, with large n. The resulting sho…
General features of the energy landscape in Lennard-Jones like model liquids
L. Angelani, G. Ruocco, M. Sampoli +1
Features of the energy landscape sampled by supercooled liquids are numerically analyzed for several Lennard-Jones like model systems. The properties of quasisaddles (minima of the…
Crossover between Equilibrium and Shear-controlled Dynamics in Sheared Liquids
L. Angelani, G. Ruocco, F. Sciortino +2
We present a numerical simulation study of a simple monatomic Lennard-Jones liquid under shear flow, as a function of both temperature and shear rate. By investigating different ob…
Quasi-saddles as relevant points of the potential energy surface in the dynamics of supercooled liquids
L. Angelani, R. Di Leonardo, G. Ruocco +2
The supercooled dynamics of a Lennard-Jones model liquid is numerically investigated studying relevant points of the potential energy surface, i.e. the minima of the square gradien…
Off-equilibrium dynamics in the energy landscape of a simple model glass
R. Di Leonardo, L. Angelani, G. Parisi +3
The aging dynamics of a simple model glass is numerically investigated observing how it takes place in the potential energy landscape . Partitioning the landscape in basins of m…
A stroll in the energy landscape
Antonio Scala, Luca Angelani, Roberto Di Leonardo +2
We review recent results on the potential energy landscape (PES) of model liquids. The role of saddle-points in the PES in connecting dynamics to statics is investigated, confirmin…
