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…
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…
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…
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…
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…
