Correlation effects on resonant tunneling in one-dimensional quantum wires
arXiv:cond-mat/0403655 · doi:10.1103/PhysRevB.71.041302
Abstract
We study resonant tunneling in a Luttinger liquid with a double barrier enclosing a dot region. Within a microscopic model calculation the conductance G as a function of temperature T is determined over several decades. We identify parameter regimes in which the peak value G_p(T) shows distinctive power-law behavior. For intermediate dot parameters G_p behaves in a non-universal way.
