## TL;DR

This paper investigates how synthetic gauge potentials influence vortex generation and transport in Bose-Einstein condensates confined in double-well potentials, revealing enhanced vortex creation and altered dynamics compared to harmonic traps.

## Contribution

It demonstrates the impact of artificial gauge potentials on vortex formation, transport, and critical magnetic fields in double-well condensates, providing new insights into vortex control.

## Key findings

- Vortex generation is enhanced with synthetic gauge potentials.
- Vortex traverse time depends on well height.
- Lower critical magnetic field needed for vortex injection in double-well.

## Abstract

We demonstrate an enhancement in the vortex generation when artificial gauge potential is introduced to condensates confined in a double well potential. This is due to the lower energy required to create a vortex in the low condensate density region within the barrier. Furthermore, we study the transport of vortices between the two wells, and show that the traverse time for vortices is longer for the lower height of the well. We also show that the critical value of synthetic magnetic field to inject vortices into the bulk of the condensate is lower in the double-well potential compared to the harmonic confining potential.
