Avalanche Size and Interevent Time Statistics in Amorphous System
Thomas Muhren, Roberto Benzi, Mauro Sbragaglia +2
The intermittent, stick-slip flow of amorphous systems is characterized by avalanches whose statistical properties display robust power-laws. In this paper, we study avalanche stat…
The Allee Effect in Compressible Flows
Jonathan Bauermann, Roberto Benzi, David R. Nelson +1
Microbes in marine environments are often confined to thin near-surface layers while being advected by turbulent flows. Because such constrained advection generates an effectively…
Freezing lakes as analogue models of CDM cosmology and beyond
Lorens F. Niehof, Ananya Venkatasubramanian, Federico Toschi +1
We extend previous conduction-based analogies between ice growth in a lake and cosmological expansion by incorporating buoyancy-driven heat transport. Reformulating the Stefan prob…
Experimental investigation into Lagrangian statistics of droplets in homogeneous isotropic turbulence
Lu Li, Yi-Bao Zhang, Yaning Fan +2
We experimentally investigate the Lagrangian dynamics of finite-sized, neutrally buoyant droplets in homogeneous isotropic turbulence. The droplet size follows a log-normal distrib…
Inertial rotation of a small oblate spheroid in a simple shear flow
Ziqi Wang, Xander M. de Wit, Davide Di Giusto +5
We compare experiments and fully-resolved particle simulations designed to match the experimental conditions of a weakly inertial, neutrally buoyant, moderately oblate spheroid in…
Non-reciprocal coalescence-breakup dynamics in concentrated emulsions
Ivan Girotto, Andrea Scagliarini, Lei Yi +3
Dense stabilized emulsions are mixtures of immiscible fluids where the high-volume fraction droplet dispersed phase is stabilized against coalescence by steric interactions. The pr…
Noise-enabled goal attainment in crowded collectives
Lucy Liu, Justin Werfel, Federico Toschi +1
In crowded environments, individuals must navigate around other occupants to reach their destinations. Understanding and controlling traffic flows in these spaces is relevant for c…
Higher-curvature corrections and the endpoint of black hole evaporation in gravitational effective field theory
Lorens F. Niehof, Sjors Heefer, Andrea Fuster +1
The endpoint of black hole evaporation remains uncertain once the semiclassical description approaches the Planck scale. In this work we study late-stage evaporation within four-di…
Odd wave turbulence
Xander M. de Wit, Léo Touzo, Sébastien Galtier +3
Wave turbulence describes the statistical dynamics of weakly interacting waves in out-of-equilibrium systems. These systems are out of equilibrium because forcing and dissipation o…
Stochastic resonance of rotating particles in turbulence
Ziqi Wang, Xander M. de Wit, Roberto Benzi +4
The chaotic dynamics of small-scale vorticity plays a key role in understanding and controlling turbulence, with direct implications for energy transfer, mixing, and coherent struc…
Turbulent mixing controls fixation of growing antagonistic populations
Jonathan Bauermann, Roberto Benzi, David R. Nelson +2
Unlike coffee and cream that homogenize when stirred, growing micro-organisms (e.g., bacteria, baker's yeast) can actively kill each other and avoid mixing. How do such antagonisti…
Divergence of critical fluctuations on approaching catastrophic phase inversion in turbulent emulsions
Lei Yi, Ivan Girotto, Federico Toschi +1
Catastrophic phase inversion, the sudden breakdown of a dense emulsion, occurs when the dispersed majority phase irreversibly exchanges role with the continuous minority phase. Thi…
Finite-size effects on bacterial population expansion under controlled fow conditions
Francesca Tesser, Jos C. H. Zeegers, Herman J. H. Clercx +2
The expansion of biological species in natural environments is usually described as the combined effect of individual spatial dispersal and growth. In the case of aquatic ecosystem…
