Phys. Rev. B 76, 125316 (2007) [4 pages]Charging of a quantum dot coupled to Luttinger-liquid leadsSee Also: Publisher's Note Received 13 July 2007; published 19 September 2007; publisher error corrected 24 September 2007 Luttinger-liquid behavior of one-dimensional correlated electron systems is characterized by power-law scaling of a variety of physical observables with exponents determined by a single interaction dependent parameter K. We suggest a setup to study Luttinger-liquid behavior in quantum wires which allows us to determine K from two independent measurements: transport through a quantum dot embedded in the wire and the charge on the dot. Consistency of the two K’s for a single probe would provide strong experimental evidence for the Luttinger-liquid paradigm. © 2007 The American Physical Society URL:
