“…Another dramatic manifestation of the LL properties in the behavior of TP is the appearance of the KFP through the renormalized reflection amplitude at the QPC |r * |, which is completely different from the results shown in Refs. [57][58][59][60].…”

In this Letter we investigate properties of a quantum impurity model in the presence of additional many-body interactions between mobile carriers. The fundamental question which is addressed here is how the interactions in charge and spin sectors of itinerant system affect the quantum impurity physics in the vicinity of the intermediate coupling fixed point. To illustrate the general answer to this question we discuss a two channel charge Kondo circuit model. We show that the electronelectron interactions resulting in formation of a massive spin mode in the itinerant electrons sub-set drive the system away from the unstable Non-Fermi liquid (NFL) fixed point to the stable Fermi liquid (FL) regime. We discuss thermoelectric response as a benchmark for the NFL-FL crossover.

“…В этом случае электроны в ЛЖ и в массивном проводнике с каждой стороны потенциального барьера находятся в состоянии термодинамического равновесия и их электрохимические потенциалы совпадают [8]. В работе [9] рассчитан коэффициент Зеебека системы, состоящей из кванто-вой точки между двумя латтинжеровскими жидкостями. Термоэлектрический транспорт в подобной системе, в которой вместо одномерных проводников использованы краевые состояния дробного квантового эффекта Холла, исследован в работе [10].…”

The thermopower of a Luttinger liquid with a potential barrier is calculated. The long-range nature of the electron-electron interaction is taken into account. It is shown that an increase of the interaction range qualitatively changes the temperature dependence of the thermopower. At low temperatures, the Seebeck coefficient of the Luttinger liquid is significantly less than the corresponding coefficient of a one-dimensional Fermi gas. With increasing temperature, the thermopower increases rapidly and may exceed that of the Fermi gas. The results obtained are in qualitative agreement with experimental data for quasi-one-dimensional 5-nm-thick InSb wires.
