Microphase Separation in Quorum-Sensing Active Particles with Competing Interactions
Michele Antonioli, Nicoletta Gnan, Claudio Maggi
Standard quorum-sensing models in active matter exhibit collective phenomena such as motility-induced phase separation. Here, we show that incorporating competing sensing ranges--…
Multiple temperatures and melting of a colloidal active crystal
Helena Massana-Cid, Claudio Maggi, Nicoletta Gnan +2
Thermal fluctuations constantly and evenly excite all vibrational modes in an equilibrium crystal. As the temperature rises, these fluctuations promote the formation of defects and…
Probing temperature-responsivity of microgels and its interplay with a solid surface by superresolution microscopy and numerical simulations
Xhorxhina Shaulli, Rodrigo Rivas-Barbosa, Maxime Jolisse Bergman +4
Superresolution microscopy has become a powerful tool to investigate the internal structure of complex colloidal and polymeric systems, such as microgels, at the nanometer scale. T…
Critical behavior of quorum-sensing active particles
Nicoletta Gnan, Claudio Maggi
It is still a debated issue whether all critical active particles belong to the same universality class. Here we numerically study the critical behavior of quorum sensing active pa…
Critical active dynamics is captured by a colored-noise driven field theory
Claudio Maggi, Nicoletta Gnan, Matteo Paoluzzi +2
We numerically investigate the correlation function, the response and the breakdown of the Fluctuation-Dissipation Theorem (FDT) in active particles close to the motility-induced c…
Effective potentials induced by mixtures of patchy and hard co-solutes
Philip H. Handle, Emanuela Zaccarelli, Nicoletta Gnan
The addition of co-solutes to colloidal suspensions is often employed to induce tunable depletion interactions. In this work we investigate effective colloidal interactions arising…
