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…

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…

Velocity and confinement of edge plasmons in HgTe-based 2D topological insulators
Alexandre Gourmelon, Elric Frigerio, Hiroshi Kamata +10
High-frequency transport in the edge states of the quantum spin Hall (QSH) effect has to date rarely been explored, though it could cast light on the scattering mechanisms taking p…
