Coexistence of metallic edge states and anti-ferromagnetic ordering in correlated topological insulators
A. Amaricci, A. Valli, G. Sangiovanni +2
We investigate the emergence of anti-ferromagnetic ordering and its effect on the helical edge states in a quantum spin Hall insulator, in the presence of strong Coulomb interactio…
Strong Correlation Effects on Topological Quantum Phase Transitions in Three Dimensions
A. Amaricci, J. C. Budich, M. Capone +2
We investigate the role of short-ranged electron-electron interactions in a paradigmatic model of three dimensional topological insulators, using dynamical mean-field theory and fo…
Negativity of the excess noise in a quantum wire capacitively coupled to a gate
F. Dolcini, B. Trauzettel, I. Safi +1
The electrical current noise of a quantum wire is expected to increase with increasing applied voltage. We show that this intuition can be wrong. Specifically, we consider a single…
Transport properties of single channel quantum wires with an impurity: Influence of finite length and temperature on average current and noise
Fabrizio Dolcini, Bjoern Trauzettel, Ines Safi +1
The inhomogeneous Tomonaga Luttinger liquid model describing an interacting quantum wire adiabatically coupled to non-interacting leads is analyzed in the presence of a weak impuri…
Transport theory of carbon nanotube Y junctions
R. Egger, B. Trauzettel, S. Chen +1
We describe a generalization of Landauer-Büttiker theory for networks of interacting metallic carbon nanotubes. We start with symmetric starlike junctions and then extend our appro…
How Irrelevant Operators affect the Determination of Fractional Charge
A. Koutouza, H. Saleur, B. Trauzettel
We show that the inclusion of irrelevant terms in the Hamiltonian describing tunneling between edge states in the fractional quantum Hall effect can lead to a variety of non pertur…
