Journal ArticleDOI
Observation of Half-Quantum Vortices in Topological Superfluid ^{3}He.
S. Autti,Vladimir V. Dmitriev,J. T. Mäkinen,A. A. Soldatov,Grigory Volovik,Grigory Volovik,A. N. Yudin,V. V. Zavjalov,Vladimir Eltsov +8 more
TL;DR: An observation of half-quantum vortices (HQVs) in the polar phase of superfluid ^{3}He-A, providing a pathway for studies of unpaired Majorana modes bound to the HQV cores in the Polar-distorted A phase.
Journal ArticleDOI
Half-quantum vortices and walls bounded by strings in the polar-distorted phases of topological superfluid 3He
J. T. Mäkinen,Vladimir V. Dmitriev,J. Nissinen,J. Rysti,Grigory Volovik,Grigory Volovik,A. N. Yudin,Kun Zhang,Kun Zhang,Vladimir Eltsov +9 more
TL;DR: In this paper, the authors show that halfquantum vortices (HQVs)-linear topological defects carrying half quantum of circulation-survive transitions from the polar phase to other superfluid phases with polar distortion.
Journal ArticleDOI
AC Josephson effect between two superfluid time crystals
S. Autti,S. Autti,Pekka Heikkinen,Pekka Heikkinen,J. T. Mäkinen,J. T. Mäkinen,Grigori Volovik,Grigori Volovik,V. V. Zavjalov,V. V. Zavjalov,Vladimir Eltsov +10 more
TL;DR: In this paper, two adjacent quantum time crystals implemented by two magnon condensates in the superfluid B-phase of helium-3 are observed to coherently exchange magnons as a manifestation of the AC Josephson effect.
Journal ArticleDOI
Half-quantum vortices and walls bounded by strings in the polar-distorted phases of topological superfluid $^3$He
J. T. Mäkinen,Vladimir V. Dmitriev,J. Nissinen,J. Rysti,Grigory Volovik,A. N. Yudin,Kun Zhang,Vladimir Eltsov +7 more
TL;DR: In this paper, it was shown that half-quantum vortices (HQVs) survive transitions from the polar phase to other superfluid phases with polar distortion, and that HQV cores in 2D systems should harbor non-Abelian Majorana modes.
Journal ArticleDOI
Exceeding the Landau speed limit with topological Bogoliubov Fermi surfaces
S. Autti,S. Autti,J. T. Mäkinen,J. T. Mäkinen,J. Rysti,Grigory Volovik,Grigory Volovik,V. V. Zavjalov,V. V. Zavjalov,Vladimir Eltsov +9 more
TL;DR: In this article, the authors showed that topological superfluid 3He can flow without friction in a phase which possesses a line of zero energy in the excitation spectrum, although the Landau's limit for superflow is zero.
