We study theoretically the current-voltage characteristics, shot noise, and full counting statistics
of a quantum wire double barrier structure. We model each wire segment by a spinless
Luttinger liquid. Within the sequential tunneling approach, we describe the system’s dynamics
using a master equation. We show that at finite bias the nonequilibrium distribution of plasmons
in the central wire segment leads to increased average current, enhanced shot noise, and full counting
statistics corresponding to a super-Poissonian process. These effects are particularly pronounced
in the strong interaction regime, while in the noninteracting case we recover results obtained
earlier using detailed balance arguments.
