Tunneling into Nonequilibrium Luttinger Liquid with Impurity

Understand

We evaluate tunneling rates into/from a voltage biased quantum wire containing weak backscattering defect.

• Interacting electrons in such a wire form a true nonequilibrium state of the Luttinger liquid (LL).
• This state is created due to inelastic electron backscattering leading to the emission of nonequilibrium plasmons with typical frequency $\hbar \omega \leq U$.
• The tunneling rates are split into two edges.
