We present preliminary studies of transverse resonances in a thin disk of aerogel filled with normal and superfluid 4He in the temperature range 1.4 to 3 K. We observed a broad temperature independent mode in the normal phase and three narrow critica

The B phase of 3 He exhibits spontaneously broken relative spin-orbit symmetry (sBsos), i.e. the symmetry is broken only under a relative rotation of spin and orbital axes. This leads to the possibility of exciting spin waves by mechanical oscillatio

We have made simultaneous torsional oscillator and transverse cw NMR (at $\ensuremath{\sim}165\mathrm{kHz}$) studies of the superfluid phase of ${}^{3}\mathrm{He}$ in aerogel glasses of 1% and 2% of solid density. NMR occurs over a range of frequency

We give a full account of our extensive measurements of vortex mutual friction in rotating superfluid 3He, in both the A- and B-phases. The B-phase results are in qualitative agreement with a theory based on the concept of "spectral flow"; the agreem

The Universe contains much more matter than antimatter, which is probably the result of processes in the early Universe in which baryon number was not conserved. These processes may have occurred during the electroweak phase transition, when elementa

We have measured the resistive and reactive mutual friction coefficients in rotating superfluid ${}^{3}\mathrm{H}\mathrm{e}\ensuremath{-}A$ at $29.3\mathrm{bars}$ pressure. The results agree with those predicted from the equation of orbital hydrodyna

We have investigated transverse continuous wave NMR in a geometry where the modes are influenced by susceptibility anisotropy. The helium sample is separated by mylar foils into layers 12 μm thick perpendicular to the external dc magnetic field. In

The equations decribing the spin dynamics of 3 He-A have been generalised to allow for the effect of susceptibility anisotropy on the Leggett-Takagi damping. Analytical and numerical solutions have been obtained for the configuration where1 is locked
