Exotic surface states in hybrid structures of topological insulators and Weyl semimetals
Stefan Juergens, Björn Trauzettel
Topological insulators (TIs) and Weyl semimetals (WSMs) are two realizations of topological matter usually appearing separately in nature. However, they are directly related to eac…
Screening properties and plasmons of Hg(Cd)Te quantum wells
Stefan Juergens, Paolo Michetti, Björn Trauzettel
Under certain conditions, Hg(Cd)Te quantum wells (QWs) are known to realize a time-reversal symmetric, two-dimensional topological insulator phase. Its low-energy excitations are w…
Plasmons due to the interplay of Dirac and Schrödinger fermions
Stefan Juergens, Paolo Michetti, Björn Trauzettel
We study the interplay between Dirac and Schrödinger fermions in the polarization properties of a two-dimensional electron gas (2DEG). Specifically, we analyze the low-energy secto…
Thermoelectric performance of a driven double quantum dot
Stefan Juergens, Federica Haupt, Michael Moskalets +1
In this paper we investigate the thermoelectric performance of a double-dot device driven by time-dependently modulated gate voltages. We show that if the modulation frequency Ω is…
Single-particle interference versus two-particle collisions
Stefan Juergens, Janine Splettstoesser, Michael Moskalets
We consider a mesoscopic circuit in the quantum Hall effect regime comprising two synchronized single-particle sources emitting particles into a Mach-Zehnder interferometer. While…
