Magnon Bose-Einstein condensates: from time crystals and quantum chromodynamics to vortex sensing and cosmology
Jere T. Mäkinen, Samuli Autti, Vladimir B. Eltsov
Under suitable experimental conditions collective spin-wave excitations, magnons, form a Bose-Einstein condensate (BEC) where the spins precess with a globally coherent phase. Bose…
Superfluid He as a rigorous test bench for different damping models in nanoelectromechanical resonators
Timo Kamppinen, Jere T. Mäkinen, Vladimir B. Eltsov
We have used nanoelectromechanical resonators to probe superfluid He at different temperature regimes, spanning over four orders of magnitude in damping. These regimes are char…
AC Josephson effect between two superfluid time crystals
Samuli Autti, Petri J. Heikkinen, Jere T. Mäkinen +3
Quantum time crystals are systems characterised by spontaneously emerging periodic order in the time domain. A range of such phases has been reported. The concept has even been dis…
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…
Quasiparticle scattering measurements of laminar and turbulent vortex flow in the spin-down of superfluid 3He-B
Jaakko Hosio, Vladimir Eltsov, Matti Krusius +1
The dynamics of quantized vortices is studied in superfluid 3He-B after a rapid stop of rotation. We use Andreev reflection of thermal excitations to monitor vortex motion with qua…
