Fractional charge oscillations in quantum spin Hall quantum dots
N. Traverso Ziani, C. Fleckenstein, G. Dolcetto +1
We show that correlated two-particle backscattering can induce fractional charge oscillations in a quantum dot built at the edge of a two-dimensional topological insulator by means…
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…
Second quantization of Leinaas-Myrheim anyons in one dimension and their relation to the Lieb-Liniger model
Thore Posske, Björn Trauzettel, Michael Thorwart
In one spatial dimension, anyons in the original description of Leinaas and Myrheim are formally equivalent to locally interacting bosons described by the Lieb-Liniger model. This…
The chiral anomaly in real space
Christoph Fleckenstein, Niccolò Traverso Ziani, Björn Trauzettel
The chiral anomaly is based on a non-conserved chiral charge and can happen in Dirac fermion systems under the influence of external electromagnetic fields. In this case, the spect…
