A quantum dissipative system is studied based on a model constructed from q
uantum dots coupled to a one-dimensional (1D) quantum wire via a Coulomb in
teraction between them. In this model, the quantum dots are approximated by
a symmetric double-well potential. We assume that the quantum wire is in s
pinless Tomonaga-Luttinger (TL) liquid states. It is shown that. ill this s
ystem, there is a transition from diffusion to localization for a tunneling
electron in the double well. We obtain the Localization condition that rel
ates tile TL parameter with those parameters characterizing the quantum dot
s and the 1D quantum wire. The implication of our results for experimental
identification of a TL liquid is discussed.
