Persistent current oscillations in a double-ring quantum gas

Vorticity in closed quantum fluid circuits is known to arise the form of persistent currents. In this work, we develop a method engineer transport quantized vorticity between density-coupled ring-shaped atomic Bose-Einstein condensates experimentally accessible regimes. Introducing tunable weak link rings, observe and characterize controllable periodic transfer current investigate role temperature on suppressing these oscillations via range complementary state-of-the-art numerical methods. Our setup paves way for precision measurements local acceleration rotation.
