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…
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…
Superconducting proximity effect in three-dimensional topological insulators in the presence of a magnetic field
Pablo Burset, Bo Lu, Grigory Tkachov +3
The proximity induced pair potential in a topological insulator-superconductor hybrid features an interesting superposition of a conventional spin-singlet component from the superc…
Quantum interference of edge supercurrents in a two-dimensional topological insulator
G. Tkachov, P. Burset, B. Trauzettel +1
Josephson weak links made of two-dimensional topological insulators (TIs) exhibit magnetic oscillations of the supercurrent that are reminiscent of those in superconducting quantum…
Transport properties of double quantum dots with electron-phonon coupling
Stefan Walter, Björn Trauzettel, Thomas L. Schmidt
We study transport through a double quantum dot system in which each quantum dot is coupled to a phonon mode. Such a system can be realized, e.g., using a suspended carbon nanotube…
