| I will present a short review of few phenomena, we have studied experimentally in superfluid 3He, which results can be relevent for cosmological theory. First of all it is Grenoble and Helsinki experiments, where the vortex strings creation have been observed after the fast second order transition. The Kibble Zurek theory of cosmic strings creation has been approved in these experiments. Secondary, I will discuss Manchester experiment of vortex viscosity at the limit of very low temperatures. The quasiparticles creation from vacuum have been observed by analogy of bariogenesis in univerce. And finally, I will present the discussion about the origin of cosmological constant in superfluid 3He. |
