Three-disk microswimmer in a supported fluid membrane

Yui Ota, Yuto Hosaka, Kento Yasuda +1

A model of three-disk micromachine swimming in a quasi two-dimensional supported membrane is proposed. We calculate the average swimming velocity as a function of the disk size and…

Observation of topological superconductivity on the surface of an iron-based superconductor

Peng Zhang, Koichiro Yaji, Takahiro Hashimoto +8

Topological superconductors, whose edge hosts Majorana bound states or Majorana fermions that obey non-Abelian statistics, can be used for low-decoherence quantum computations. Mos…

Superconductivity in an electron band just above the Fermi level: possible route to BCS-BEC superconductivity

Kozo Okazaki, Yoshiaki Ito, Yuichi Ota +10

Conventional superconductivity follows Bardeen-Cooper-Schrieffer(BCS) theory of electrons-pairing in momentum-space, while superfluidity is the Bose-Einstein condensation(BEC) of a…
