Characterization of helical Luttinger liquids in microwave stepped-impedance edge resonators
Alexandre Gourmelon, Hiroshi Kamata, Jean-Marc Berroir +3
Coulomb interaction has important consequences on the physics of quantum spin Hall edge states, weakening the topological protection via two-particle scattering and renormalizing b…
Half-Integer Shapiro Steps in a Short Ballistic InAs Nanowire Josephson Junction
Kento Ueda, Sadashige Matsuo, Hiroshi Kamata +6
We report on half-integer Shapiro steps observed in an InAs nanowire Josephson junction. We observed the Shapiro steps of the short ballistic InAs nanowire Josephson junction and f…
Dynamical separation of bulk and edge transport in HgTe-based 2D topological insulators
Matthieu C. Dartiailh, Simon Hartinger, Alexandre Gourmelon +11
Topological effects in edge states are clearly visible on short lengths only, thus largely impeding their studies. On larger distances, one may be able to dynamically enhance topol…
Strong Electron-Electron Interactions of a Tomonaga--Luttinger Liquid Observed in InAs Quantum Wires
Yosuke Sato, Sadashige Matsuo, Chen-Hsuan Hsu +12
We report strong electron-electron interactions in quantum wires etched from an InAs quantum well, a material known to have strong spin-orbit interactions. We find that the current…
Anomalous modulation of Josephson radiation in nanowire-based Josephson junctions
Hiroshi Kamata, Russell S. Deacon, Sadashige Matsuo +6
We investigate the Josephson radiation of nanowire (NW)-based Josephson junctions in a parallel magnetic field. The Josephson junction made of an InAs NW with superconducting Al le…
Cooper-pair splitting in two parallel InAs nanowires
Shoji Baba, Christian Jünger, Sadashige Matsuo +9
We report on the fabrication and electrical characterization of an InAs double - nanowire (NW) device consisting of two closely placed parallel NWs coupled to a common superconduct…
