Binary Channel Turbulence in Two-Component Bose-Einstein Condensates*

Bose-Einstein condensates (BECs) serve as a powerful testbed for studying quantum turbulence and nonlinear dynamics. The ability to investigate multicomponent systems within flexible confinement geometries offers unique opportunities for generating, detecting, and analyzing quantum hydrodynamics. In this work, we employ a two-component BEC in an elongated geometry to generate binary turbulence through phase winding and differential forces. We observe the subsequent dynamics, which lead to strong soliton formation.

This experimental study complements contemporary research on quantum turbulence by highlighting the characteristic effects of a channel geometry. It provides important benchmark data for accompanying numerical and analytical studies into the nature of instabilities in BECs.
