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…
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…
Out of equilibrium density dynamics of a quenched fermionic system
S. Porta, F. M. Gambetta, F. Cavaliere +2
Using a Luttinger liquid theory we investigate the time evolution of the particle density of a one-dimensional fermionic system with open boundaries and subject to a finite duratio…
Correlation and current anomalies in helical quantum dots
Christophe De Beule, Niccolo T. Ziani, Mohammad Zarenia +2
We theoretically investigate the ground-state properties of a quantum dot defined on the surface of a strong three-dimensional time-reversal invariant topological insulator. Confin…
