Active Turbulence
Ricard Alert, Jaume Casademunt, Jean-François Joanny
Active fluids exhibit spontaneous flows with complex spatiotemporal structure, which have been observed in bacterial suspensions, sperm cells, cytoskeletal suspensions, self-propel…
Scaling regimes of active turbulence with external dissipation
Berta Martínez-Prat, Ricard Alert, Fanlong Meng +5
Active fluids exhibit complex turbulent-like flows at low Reynolds number. Recent work predicted that 2d active nematic turbulence follows universal scaling laws. However, experime…
Universal scaling of active nematic turbulence
Ricard Alert, Jean-François Joanny, Jaume Casademunt
A landmark of turbulence is the emergence of universal scaling laws, such as Kolmogorov's scaling of the kinetic energy spectrum of inertial turbulence with the…
Hydrodynamic instabilities, waves and turbulence in spreading epithelia
C. Blanch-Mercader, J. Casademunt
We present a hydrodynamic model of spreading epithelial monolayers as polar viscous fluids, with active contractility and traction on the substrate. The combination of both active…
Formation of metastable phases by spinodal decomposition
Ricard Alert, Pietro Tierno, Jaume Casademunt
Metastable phases may be spontaneously formed from other metastable phases through nucleation. Here we demonstrate the spontaneous formation of a metastable phase from an unstable…
Landscape-Inversion Phase Transition in Dipolar Colloids: Tuning the Structure and Dynamics of 2D Crystals
Ricard Alert, Jaume Casademunt, Pietro Tierno
We study the 2D crystalline phases of paramagnetic colloidal particles with dipolar interactions and constrained on a periodic substrate. Combining theory, simulation, and experime…
