Landau levels in a time-dependent magnetic field: the Madelung fluid perspective
Nicolas Perez, Eyal Heifetz
We revisit the quantum dynamics of a charged particle in a time-dependent magnetic field, a fundamental problem exhibiting rich non-adiabatic behaviour, from the complementary pers…
A conservative low-order model for Boussinesq baroclinic fronts
Nadav Yovel, Eyal Heifetz
The internal dynamics of baroclinic fronts are governed by a fundamental interplay: turbulent eddies systematically act to disrupt thermal wind balance, with baroclinic eddies flat…
Observation of Large-Scale Kelvin-Helmholtz Instability Wave Driven by a Coronal Mass Ejection
Leon Ofman, Olga Khabarova, Ryun-Yong Kwon +3
The Kelvin-Helmholtz instability (KHI) can occur when there is a relative motion between two adjacent fluids. In the case of magnetized plasma, the shear velocity must exceed the l…
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…
