Vortex-bound solitons in topological superfluid He
J. T. Mäkinen, K. Zhang, V. B. Eltsov
The different superfluid phases of He are described by -wave order parameters that include anisotropy axes both in the orbital and spin spaces. The anisotropy axes character…
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…
Mutual friction in superfluid He-B in the low-temperature regime
J. T. Mäkinen, V. B. Eltsov
We measure the response of a rotating sample of superfluid He-B to spin-down to rest in the zero-temperature limit. Deviations from perfect cylindrical symmetry in the flow env…
Bose-Einstein condensation of magnons and spin superfluidity in the polar phase of He
S. Autti, V. V. Dmitriev, J. T. Mäkinen +5
The polar phase of He, which is topological spin-triplet superfluid with the Dirac nodal line in the spectrum of Bogolubov quasiparticles, has been recently stabilized in a nan…
No Effect of Steady Rotation on Solid He in a Torsional Oscillator
M. J. Fear, P. M. Walmsley, D. E. Zmeev +2
We have measured the response of a torsional oscillator containing polycrystalline hcp solid He to applied steady rotation in an attempt to verify the observations of several…
Observation of half-quantum vortices in topological superfluid 3He
S. Autti, V. V. Dmitriev, J. T. Mäkinen +5
One of the most sought-after objects in topological quantum matter systems is a vortex carrying half a quantum of circulation. They were originally predicted to exist in superfluid…
Andreev reflection in rotating superfluid He-B
V. B. Eltsov, J. J. Hosio, M. Krusius +1
Andreev reflection of quasiparticle excitations from quantized line vortices is reviewed in the isotropic B phase of superfluid He in the temperature regime of ballistic quasip…
Propagation of thermal excitations in a cluster of vortices in superfluid 3He-B
J. J. Hosio, V. B. Eltsov, R. de Graaf +3
We describe the first measurement on Andreev scattering of thermal excitations from a vortex configuration with known density, spatial extent, and orientations in 3He-B superfluid.…
