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 of magnetic barriers. The result nicely complements recent works where those fractional oscillations were predicted in the strong-coupling regime. Moreover, since by...

The competition between Friedel and Wigner oscillations in the density of strongly interacting carbon nanotubes is inspected within the Luttinger liquid picture. The power laws of the low temperature density oscillations are different from the usual case of quantum dots defined in quantum wires. Temperature plays an important role in the...
