The flow of currents between macroscopic quantum systems, such as superfluids or superconductors, that are weakly connected will depend on the relative quantum phase describing each condensate. Such effects, which govern superconducting tunnel junctions, are much more difficult to observe directly in superfluids such as liquid helium-3. Backhaus et al. (p. 1435) determined the current-phase relation directly for superfluid helium by using a membrane array of 4225 apertures to connect two reservoirs, and they observed the transition with increasing temperature from linear to sinusoidal behavior.
