Theory of Coulomb blockade in Tomonaga-Luttinger liquid connected with Fermi liquids
A self-consistent microscopic theory of Coulomb blockade in Tomonaga-Luttinger liquid island connected with Fermi liquid electrodes is proposed. The charging effect as well as Tomonaga-Luttinger nature are treated in consistent manner by bosonization technique with zero mode under open boundary condition. Tunneling current is calculated up to the lowest order. It is shown that the current is expressed in terms of the local spectral density modified by the open boundary condition as well as charging effect. For the ultrasmall island, the value of power-law exponent is not always definite.
