Vortex-mediated relaxation of magnon BEC into light Higgs quasiparticles
S. Autti, P. J. Heikkinen, S. M. Laine +4
A magnon Bose-Einstein condensate in superfluid He is a fine instrument for studying the surrounding macroscopic quantum system. At zero temperature, the BEC is subject to a fe…

Propagation of self-localised Q-ball solitons in the He universe
S. Autti, P. J. Heikkinen, G. E. Volovik +2
In relativistic quantum field theories, compact objects of interacting bosons can become stable owing to conservation of an additive quantum number . Discovering such -balls…

Gravity waves on the surface of topological superfluid 3He-B
V. B. Eltsov, P. J. Heikkinen, V. V. Zavjalov
We have observed waves on the free surface of 3He-B sample at temperatures below 0.2mK. The waves are excited by vibrations of the cryostat and detected by coupling the surface to…
