Time reversal symmetry broken fractional topological phases at zero magnetic field
Tobias Meng, Eran Sela
We extend the coupled-wire construction of quantum Hall phases, and search for fractional topological insulating states in models of weakly coupled wires at zero external magnetic…
Strongly Interacting Holes in Ge/Si Nanowires
Franziska Maier, Tobias Meng, Daniel Loss
We consider holes confined to Ge/Si core/shell nanowires subject to strong Rashba spin-orbit interaction and screened Coulomb interaction. Such wires can, for instance, serve as ho…
Helical nuclear spin order in a strip of stripes in the Quantum Hall regime
Tobias Meng, Peter Stano, Jelena Klinovaja +1
We investigate nuclear spin effects in a two-dimensional electron gas in the quantum Hall regime modeled by a weakly coupled array of interacting quantum wires. We show that the pr…
Nuclear Spin Relaxation in Rashba Nanowires
Alexander A. Zyuzin, Tobias Meng, Viktoriia Kornich +1
We study the nuclear spin relaxation in a ballistic nanowire with hyperfine and Rashba spin-orbit interactions (SOI) and in the presence of magnetic field and electron interactions…
Non-Abelian parafermions in time-reversal invariant interacting helical systems
Christoph P. Orth, Rakesh P. Tiwari, Tobias Meng +1
The interplay between bulk spin-orbit coupling and electron-electron interactions produces umklapp scattering in the helical edge states of a two-dimensional topological insulator.…
Renormalization of anticrossings in interacting quantum wires with Rashba and Dresselhaus spin-orbit couplings
Tobias Meng, Jelena Klinovaja, Daniel Loss
We discuss how electron-electron interactions renormalize the spin-orbit induced anticrossings between different subbands in ballistic quantum wires. Depending on the ratio of spin…
