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…
Fractional statistics in anyon collisions
H. Bartolomei, M. Kumar, R. Bisognin +9
Two-dimensional systems can host exotic particles called anyons whose quantum statistics are neither bosonic nor fermionic. For example, the elementary excitations of the fractiona…
RF compressibility of topological surface and interface states in metal-hBN-Bi2Se3 capacitors
Andreas Inhofer, Taylor Wilde, Jack Duffy +9
The topological state that emerges at the surface of a topological insulator (TI) and at the TI-substrate interface are studied in metal-hBN-Bi2Se3 capacitors. By measuring the RF…
Microwave photons emitted by fractionally charged quasiparticles
R. Bisognin, H. Bartolomei, M. Kumar +8
Strongly correlated low-dimensional systems can host exotic elementary excitations carrying a fractional charge and potentially obeying anyonic statistics. In the fractional qu…
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…
A corner reflector of graphene Dirac fermions as a phonon-scattering sensor
H. Graef, Q. Wilmart, M. Rosticher +10
Dirac fermion optics exploits the refraction of chiral fermions across optics-inspired Klein-tunneling barriers defined by high-transparency p-n junctions. We consider the corner r…
