Abstract
A zero mode bosonization technique treatment of the Hamiltonian is applied to the calculation of the persistent current carried by a Luttinger liquid with a single impurity. Analytical expressions are obtained for the suppres sion of the current as function of the impurity strength and the electron-e lectron interaction. The expression in the weak limit is confirmed numerica lly. (C) 1999 Elsevier Science B.V.
