摘要：
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 nonuniversal way.
