Equatorial Waves in Rotating Bubble-Trapped Superfluids
Guangyao Li, Dmitry K. Efimkin
As the Earth rotates, the Coriolis force causes several oceanic and atmospheric waves to be trapped along the equator, including Kelvin, Yanai, Rossby, and Poincaré modes. It has b…
Kinetic theory of dark solitons with tunable friction
Hilary M. Hurst, Dmitry K. Efimkin, I. B. Spielman +1
We study controllable friction in a system consisting of a dark soliton in a one-dimensional Bose-Einstein condensate coupled to a non-interacting Fermi gas. The fermions act as im…
Brownian motion of solitons in a Bose-Einstein Condensate
L. M. Aycock, H. M. Hurst, D. K. Efimkin +4
For the first time, we observed and controlled the Brownian motion of solitons. We launched solitonic excitations in highly elongated BECs and showed that a dilute b…
Non-Markovian quantum friction of bright solitons in superfluids
Dmitry K. Efimkin, Johannes Hofmann, Victor Galitski
We explore the quantum dynamics of a bright matter-wave soliton in a quasi-one-dimensional bosonic superfluid with attractive interactions. Specifically, we focus on the dissipativ…
Moving solitons in a one-dimensional fermionic superfluid
Dmitry K. Efimkin, Victor Galitski
A fully analytical theory of a traveling soliton in a one-dimensional fermionic superfluid is developed within the framework of time-dependent self-consistent Bogoliubov-de Gennes…
