Equatorial waves in rotating bubble-trapped superfluids

G Li, DK Efimkin - Physical Review A, 2023 - APS
As the Earth rotates, the Coriolis force causes various oceanic and atmospheric waves to be
trapped along the equator, including Kelvin, Yanai, Rossby, and Poincaré modes. It has …

Triangular vortex lattices and giant vortices in rotating bubble Bose-Einstein condensates

AC White - Physical Review A, 2024 - APS
We show that three-dimensional spherical-shell condensates respond to rotation by forming
two aligned triangular Abrikosov-like vortex lattices on each hemispherical surface. The …

Rossby–Haurwitz wave in a rotating bubble-shaped Bose–Einstein condensate

H Saito, M Hayashi - Journal of the Physical Society of Japan, 2023 - journals.jps.jp
A Rossby–Haurwitz (RH) wave is an excitation mode of a fluid on a rotating spherical
surface, which propagates westward in the rotating frame of reference. Motivated by the …

Faraday waves on a bubble-trapped Bose-Einstein-condensed binary mixture

L Brito, L Tomio, A Gammal - Physical Review A, 2023 - APS
By studying the dynamic stability of Bose-Einstein-condensed binary mixtures trapped on
