Universal conductance dips and fractional excitations in a two-subband quantum wire
Chen-Hsuan Hsu, Flavio Ronetti, Peter Stano +2
We theoretically investigate a quasi-one-dimensional quantum wire, where the lowest two subbands are populated, in the presence of a helical magnetic field. We uncover a backscatte…

Evidence is presented for a first-order magnetic phase transition in a gated two-dimensional semiconductor, monolayer-MoS. The phase boundary separates a spin-polarised (ferrom…
Magnetically-Confined Bound States in Rashba Systems
Flavio Ronetti, Kirill Plekhanov, Daniel Loss +1
A Rashba nanowire is subjected to a magnetic field that assumes opposite signs in two sections of the nanowire, and, thus, creates a magnetic domain wall. The direction of magnetic…
