Abstract
We demonstrate a flux locking technique using injected heat current to linearize the output of a superfluid helium-4 interferometer. A rotation flux through the interferometer loop produces a shift in the phase of the superfluid order parameter. This shift is nullified via negative feedback by a phase-shift caused by the injected heat current. The feedback signal is then a linear function of rotation flux.
