Natural Selection in the Wake of Catastrophe
Jesse Young Lin, Omer Granek, Joshua Sodicoff +3
Living organisms, from bacteria to humans, are more likely to survive if their traits enhance fitness. In populations well adapted to their environmental niches, natural selection…
How Continuous Symmetry Stabilizes the Ordered Phase of Polar Flocks
Omer Granek, Hugues Chaté, Yariv Kafri +3
We study the stability of the ordered phase of compressible polar flocks against the nucleation of counter-propagating droplets, using a combination of analytical theory, microscop…
Universal Correlations in Local Measurements Directly Probe Effective Diffusivity
Omer Granek
Measuring transport coefficients at the microscale remains challenging, often relying on indirect methods that require modeling and calibration. This article derives universal asym…
Lever rule violation and pressure imbalance in a driven granular system
Soumen Das, Anit Sane, Satyanu Bhadra +4
We study a monolayer of metal balls under periodic chiral driving in the horizontal plane. Energy dissipation occurs in this system via (i) inelastic collisions and (ii) frictional…
