Can we swim in superfluids?: Numerical demonstration of self-propulsion in a Bose-Einstein condensate

Abstract

It is numerically investigated whether a deformable object can propel itself in a superfluid. Articulated bodies and multi-component condensates are examined as swimmers. An articulated two-body swimmer cannot obtain locomotion without emitting excitations. More flexible swimmers can do so without the need to excite waves.
