Coherent charge and spin oscillations induced by local quenches in nanowires with spin-orbit coupling
F. Cavaliere, N. Traverso Ziani, F. Dolcini +2
When a local and attractive potential is quenched in a nanowire, the spectrum changes its topology from a purely continuum to a continuum and discrete portion. We show that, under…
Transport signatures of a Floquet topological transition at the helical edge
C. Fleckenstein, N. Traverso Ziani, L. Privitera +2
The manipulation of the helical edge states of two-dimensional topological insulators is crucial for the development of technological applications. Recently, an important step forw…
Interacting topological edge channels
Jonas Strunz, Jonas Wiedenmann, Christoph Fleckenstein +10
Electrical currents in a quantum spin Hall insulator are confined to the boundary of the system. The charge carriers can be described as massless relativistic particles, whose spin…
Feasible model for photo-induced interband pairing
S. Porta, L. Privitera, N. Traverso Ziani +3
Recently, it has been proposed that a mechanism for the appearance of non-equilibrium superconductivity in a resonantly driven semiconductor with repulsive interband interactions e…
