Investigate theoretically quantum transport through the “charge” Kondo circuit consisting of the quantum dot (QD) coupled weakly to an electrode at temperature T + ∆T and connected strongly to another electrode at the reference temperature T by a single-mode quantum point contact (QPC). To account for the effects of Coulomb interaction in the QD-QPC setup operating in the integer quantum Hall regime we describe the edge current in the quantum circuit by Luttinger model characterized by the Luttinger parameter g.
