General scatterings and electronic states in the quantum-wire network of moiré systems
Chen-Hsuan Hsu, Daniel Loss, Jelena Klinovaja
We investigate electronic states in a two-dimensional network consisting of interacting quantum wires, a model adopted for twisted bilayer systems. We construct general operators w…
Helical Liquids in Semiconductors
Chen-Hsuan Hsu, Peter Stano, Jelena Klinovaja +1
One-dimensional helical liquids can appear at boundaries of certain condensed matter systems. Two prime examples are the edge of a quantum spin Hall insulator and the hinge of a th…
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…
Charge transport of a spin-orbit-coupled Luttinger liquid
Chen-Hsuan Hsu, Peter Stano, Yosuke Sato +3
The charge transport of a (Tomonaga-)Luttinger liquid with tunnel barriers exhibits universal scaling: the current-voltage curves measured at various temperatures collapse into a s…
Strong Electron-Electron Interactions of a Tomonaga--Luttinger Liquid Observed in InAs Quantum Wires
Yosuke Sato, Sadashige Matsuo, Chen-Hsuan Hsu +12
We report strong electron-electron interactions in quantum wires etched from an InAs quantum well, a material known to have strong spin-orbit interactions. We find that the current…
G-factor of electrons in gate-defined quantum dots in a strong in-plane magnetic field
Peter Stano, Chen-Hsuan Hsu, Marcel Serina +3
We analyze orbital effects of an in-plane magnetic field on the spin structure of states of a gated quantum dot based in a two-dimensional electron gas. Starting with a …
