Spin textures of strongly correlated spin Hall quantum dots
G. Dolcetto, N. Traverso Ziani, M. Biggio +2
We study the spin ordering of a quantum dot defined via magnetic barriers in an interacting quantum spin Hall edge. The spin-resolved density-density correlation functions are comp…
Carbon nanotube sensor for vibrating molecules
F. Remaggi, N. Traverso Ziani, G. Dolcetto +2
The transport properties of a CNT capacitively coupled to a molecule vibrating along one of its librational modes are studied and its transport properties analyzed in the presence…
Coulomb blockade microscopy of spin density oscillations and fractional charge in quantum spin Hall dots
Giacomo Dolcetto, Niccolò Traverso Ziani, Matteo Biggio +2
We evaluate the spin density oscillations arising in quantum spin Hall quantum dots created via two localized magnetic barriers. The combined presence of magnetic barriers and spin…
Generating and controlling spin-polarized currents induced by a quantum spin Hall antidot
Giacomo Dolcetto, Fabio Cavaliere, Dario Ferraro +1
We study an electrically controlled quantum spin Hall antidot embedded in a two-dimensional topological insulating bar. Helical edge states around the antidot and along the edges o…
