Low-energy properties of fractional helical Luttinger liquids
Tobias Meng, Lars Fritz, Dirk Schuricht +1
We investigate the low-energy properties of (quasi) helical and fractional helical Luttinger liquids. In particular, we calculate the Drude peak of the optical conductivity, the de…
Non-universal conductance in quasi-helical quantum wires
Tobias Meng, Daniel Loss
In a quantum wire with ideal helical modes, the conductance is quantized in units of e^2/h, provided the wire is connected to Fermi liquid leads. We show that this universality doe…
Strongly anisotropic spin response as a signature of the helical regime in Rashba nanowires
Tobias Meng, Daniel Loss
Rashba nanowires in a magnetic field exhibit a helical regime when the spin-orbit momentum is close to the Fermi momentum, k_F \approx k_{SO}. We show that this regime is character…
Helical nuclear spin order in two-subband quantum wires
Tobias Meng, Daniel Loss
In quantum wires, the hyperfine coupling between conduction electrons and nuclear spins can lead to a (partial) ordering of both of them at low temperatures. By an interaction-enha…
