Exceeding the Landau superflow speed limit with topological Bogoliubov Fermi surfaces
S. Autti, J. T. Mäkinen, J. Rysti +3
A common property of topological systems is the appearance of topologically protected zero-energy excitations. In a superconductor or superfluid such states set the critical veloci…
Spin, orbital, Weyl and other glasses in topological superfluids
G. E. Volovik, J. Rysti, J. T. Makinen +1
One of the most spectacular discoveries made in superfluid He confined in a nanostructured material like aerogel or nafen was the observation of the destruction of the long-ran…
Effects of He film on quartz tuning forks in He at ultra-low temperatures
T. S. Riekki, J. Rysti, J. T. Mäkinen +3
In pure superfluid He-B at ultra-low temperatures, quartz tuning fork oscillator response is expected to saturate when the dissipation caused by the superfluid medium becomes s…
Half-quantum vortices and walls bounded by strings in the polar-distorted phases of topological superfluid He
J. T. Mäkinen, V. V. Dmitriev, J. Nissinen +5
Symmetries of the physical world have guided formulation of fundamental laws, including relativistic quantum field theory and understanding of possible states of matter. Topologica…
