B phase nucleation and A-B interface dynamics in superfluid 3He
… nucleation and subsequent expansion of the superfluid 3He-B phase in the metastable, hypercooled A phase. An overview of the theory of dynamical phenomena in Fermi superfluids is presented in Chapter 1 with an eye towards formulating a theory suitable for studying the dynamics of the first …

Visualisation of quantum turbulence in superfluid 3He-B using a novel 2D quasiparticle detector
… of excitation beams and quantum turbulence in superfluid 3He-B at temperatures below 200 µK. The detector was constructed from 5 arrays of 5 tuning forks mounted in a copper block to create a 25 pixel square detector of excitation flux. The detector was situated in a cell such that it could be …

Demagnetisation of solid 3He and supercritical superflow
… with two ultra low temperature experiments with superfluid 3He as medium of interest. The experiments are mostly performed at temperatures below 200uK, in the regime where superfluid quasiparticle excitations are ballistic. Recently, a novel experimental tool has been built in Lancaster - a …

Many-body physics and non-equilibrium dynamics in ultracold atomic systems
… solitonic excitations in ultracold fermionic superfluids: the first simulates recent experiments and supports the hypothesis that the solitons generated in those experiments are unstable to the formation of vortex rings; the second demonstrates how population imbalance between up and down spin …

Quasiparticle beam profile measurements in superfluid helium 3 - B
… details experiments in the ballistic regime of superfluid 3He-B at temperatures around 100 ➭K. In this thesis, the quasiparticle beam profile from a Black-Body radiator and a vibrating wire resonator is measured using a quasiparticle camera which consists of 25 tuning forks. The vibrating wire …

Critical flow velocity in super fluid 3He-B
… this thesis have measured the distortion of the superfluid energy gap in high magnetic field and the dissipation for an object in uniform linear motion through superfluid 3He-B. The latter experiments led to an astonishing discovery of no discontinuity in the dissipation for an object in uniform …

Explorations of domain walls and half quantum vortices in unconventional superconductors
… result is that, in contrast to the case of bulk superfluid 3He, half quantum vortices are shown to exist for both the time reversal symmetry broken and time-reversal intact forms of superconducting order. Then, after introducing the structure of the London free energy that effectively describes …
