  Josephson junctions are essential ingredients in the superconducting circuits
used in many existing quantum technologies. Additionally, ultracold atomic
quantum gases have also become essential platforms to study superfluidity.
Here, we explore the analogy between superconductivity and superfluidity to
present an intriguing effect caused by a thin finite barrier in a
quasi-one-dimensional toroidal spinor Bose--Einstein condensate (BEC). In this
system, the atomic current density flowing through the edges of the barrier
oscillates, such as the electrical current through a Josephson junction in a
superconductor, but in our case, there is no current circulation through the
barrier. We also show how the nontrivial broken-symmetry states of spinor BECs
change the structure of this Josephson-like current, creating the possibility
to probe the spinor symmetry, solely using measurements of this superfluid
current.
