Contribution

It introduces the concept of vortex trimers in multi-component BECs and shows how their properties can be manipulated through internal couplings.

Findings

Vortex trimer exists in three-component BECs with coherent couplings.

Shape and size of the vortex molecule are controllable.

Vortex molecules are bounded by domain walls of relative phases.

Abstract

Vortex trimer is predicted in three-component Bose-Einstein condensates with internal coherent couplings. The molecule is made by three constituent vortices which are bounded by domain walls of the relative phases. We show that the shape and the size of the molecule can be controlled by changing the internal coherent couplings.
