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…
Topological nodal line in superfluid He and the Anderson theorem
T. Kamppinen, J. Rysti, M. -M. Volard +2
Superconductivity and superfluidity with anisotropic pairing -- such as -wave in cuprates and -wave in superfluid He -- are strongly suppressed by impurities. Meanwhile,…
Suppressing the Kibble-Zurek mechanism by a symmetry-violating bias
J. Rysti, J. T. Mäkinen, S. Autti +3
The formation of topological defects in continuous phase transitions is driven by the Kibble-Zurek mechanism. Here we study the formation of single- and half-quantum vortices durin…
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…
