Magnetotunneling as a Probe of Luttinger-Liquid Behavior
Magnetotunneling as a Probe of Luttinger-Liquid Behavior
A novel method for detecting Luttinger-liquid behavior is proposed. The idea is to measure the tunneling conductance between a quantum wire and a parallel two-dimensional electron system as a function of both the potential difference between them, $V$, and an in-plane magnetic field, $B$. We show that the two-parameter dependence …
