A Swarm Coherence Mechanism for Jellyfish
Erik Gengel, Zafrir Kuplik, Dror Angel +1
We present a theory of jellyfish swarm formation and exemplify it with simulations of active Brownian particles. The motivation for our analysis is the phenomenon of jellyfish bloo…

Edge-wave phase-shifts versus normal-mode phase-tilts in an Eady problem with a sloping boundary
Julian Mak, Nili Harnik, Eyal Heifetz +2
One mechanistic interpretation of baroclinic instability is that of mutual constructive interference of Rossby edge-waves. While the two edge-waves and their relative phase-shifts…

Relating interfacial Rossby wave interaction in shear flows with Feynman's two-state coupled quantum system model for the Josephson junction
Eyal Heifetz, Nimrod Bratspiess, Anirban Guha +1
Here we show how Feynman's simplified model for the Josephson junction, as a macroscopic two-state coupled quantum system, has a one-to-one correspondence with the stable dynamics…
