Fluctuations of driven probes reveal nonequilibrium transitions in complex fluids
Danilo Forastiere, Emanuele Locatelli, Gianmaria Falasco +2
Complex fluids subjected to localized microscopic energy inputs, typical of active microrheology setups, exhibit poorly understood nonequilibrium behaviors because of the intricate…
Conformation and topology of cyclical star polymers
Davide Breoni, Emanuele Locatelli, Luca Tubiana
We study the conformation and topological properties of cyclical star polymers with ring arms, each made of beads. We find that the conformational properties of unlinked cy…
Upsurge of spontaneous knotting in polar diblock active polymers
Marin Vatin, Enzo Orlandini, Emanuele Locatelli
Spontaneous formation of knots in long polymers at equilibrium is inevitable but becomes rare in sufficiently short chains. Here, we show that knotting and knot complexity increase…
Universal time and length scales of polar active polymer melts
Mattia Alberto Ubertini, Emanuele Locatelli, Angelo Rosa
We present an in-depth multi-scale analysis of the conformations and dynamics of polar active polymers, comparing very dilute and very dense conditions. We unveil characteristic le…
