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…

Variational autoencoders understand knot topology
Anna Braghetto, Sumanta Kundu, Marco Baiesi +1
Supervised machine learning (ML) methods are emerging as valid alternatives to standard mathematical methods for identifying knots in long, collapsed polymers. Here, we introduce a…

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…
