Autor: Alles, H., Kaplinsky, J. J., Wootton, P. S., Reppy, J. D., Hook, J. R.

Publikováno v: Physica B 255 (1998) 1

We have made simultaneous torsional oscillator and transverse NMR measurements (at 165 kHz) on 3He contained within aerogels with nominal densities of 1% and 2% of solid glass. The superfluid transition is seen simultaneously by both techniques and o

Evidence for superfluid B-phase of 3He in aerogel

Autor: Alles, H., Kaplinsky, J. J., Wootton, P. S., Reppy, J. D., Naish, J. H., Hook, J. R.

Publikováno v: Phys. Rev. Lett. 83, 1367 (1999).

We have made simultaneous torsional oscillator and transverse cw NMR (at 165 kHz) studies of the superfluid phase of 3He in aerogel glasses of 1% and 2% of solid density. NMR occurs over a range of frequency extending from the Larmor frequency to hig

Momentum creation by vortices in 3He experiments as a model of primordial baryogenesis

Autor: Bevan, T. D. C., Manninen, A. J., Cook, J. B., Hook, J. R., Hall, H. E., Vachaspati, T., Volovik, G. E.

Publikováno v: Nature 386 (1997), 689

We show that recent 3He experiments at Manchester demonstrate the creation of excitation momentum (momentogenesis) by quantized vortices, a process analogous to baryogenesis within cosmic strings. Since superfluid 3He is the most complex field theore
