Sheared phase-separating binary mixtures with surface diffusion
G. Gonnella, A. Lamura
The phase-separation process of a binary mixture with order-parameter-dependent mobility under shear flow is numerically studied. The ordering is characterized by an alternate stre…
Unified analysis of Topological Defects in 2D systems of Active and Passive disks
Pasquale Digregorio, Demian Levis, Leticia F. Cugliandolo +2
We provide a comprehensive quantitative analysis of localized and extended topological defects in the steady state of 2D passive and active repulsive Brownian disk systems. We show…
Cholesteric shells: two-dimensional blue fog and finite quasicrystals
Livio Nicola Carenza, Giuseppe Gonnella, Davide Marenduzzo +2
We study the phase behaviour of a quasi-two dimensional cholesteric liquid crystal shell. We characterise the topological phases arising close to the isotropic-cholesteric transiti…
Rheology of active emulsions with negative effective viscosity
Ilario Favuzzi, Livio Nicola Carenza, Federico Corberi +3
We numerically study by lattice Boltzmann simulations the rheological properties of an active emulsion made of a suspension of an active polar gel embedded in an isotropic passive…
Work Fluctuations in the Active Ornstein- Uhlenbeck Particle model
Massimiliano Semeraro, Antonio Suma, Isabella Petrelli +2
We study the large deviations of the power injected by the active force for an Active Ornstein-Uhlenbeck Particle (AOUP), free or in a confining potential. For the free-particle ca…
Cascade or not cascade? Energy transfer and elastic effects in active nematics
Livio Nicola Carenza, Luca Biferale, Giuseppe Gonnella
We numerically study the multi-scale properties of a 2d active gel to address the energy transfer mechanism. We find that activity is able to excite long-ranged distortions of the…
