Interfering trajectories in a ballistic Andreev cavity
Pankaj Mandal, Marcel Kaschper, Fernando Dominguez +9
The conventional description of transport through the interface between a normal conductor and a superconductor reduces the system to a one-dimensional problem treating Andreev ref…
Spectral asymmetry induces a re-entrant quantum Hall effect in a topological insulator
Li-Xian Wang, Wouter Beugeling, Fabian Schmitt +5
The band inversion of topological materials in three spatial dimensions is intimately connected to the parity anomaly of two-dimensional massless Dirac fermions. At finite magnetic…
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…
Finite field transport response of a dilute magnetic topological insulator based Josephson junction
Pankaj Mandal, Nicolai Taufertshöfer, Lukas Lunczer +3
Hybrid samples combining superconductors with magnetic topological insulators are a promising platform for exploring exotic new transport physics. We examine a Josephson junction o…
Counterpropagating topological and quantum Hall edge channels
Saquib Shamim, Pragya Shekhar, Wouter Beugeling +7
The survival of the quantum spin Hall edge channels in presence of an external magnetic field has been a subject of experimental and theoretical research. The inversion of Landau l…
Emergent quantum Hall effects below mT in a two-dimensional topological insulator
Saquib Shamim, Wouter Beugeling, Jan Böttcher +7
The realization of the quantum spin Hall effect in HgTe quantum wells has led to the development of topological materials which, in combination with magnetism and superconductivity…
Interplay of Dirac nodes and Volkov-Pankratov surface states in compressively strained HgTe
David M. Mahler, Julian-Benedikt Mayer, Philipp Leubner +8
Preceded by the discovery of topological insulators, Dirac and Weyl semimetals have become a pivotal direction of research in contemporary condensed matter physics. While easily ac…
Interacting topological edge channels
Jonas Strunz, Jonas Wiedenmann, Christoph Fleckenstein +10
Electrical currents in a quantum spin Hall insulator are confined to the boundary of the system. The charge carriers can be described as massless relativistic particles, whose spin…
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…
Topological Superconductivity in a Phase-Controlled Josephson Junction
Hechen Ren, Falko Pientka, Sean Hart +9
Topological superconductors can support localized Majorana states at their boundaries. These quasi-particle excitations have non-Abelian statistics that can be used to encode and m…
