ProgrammeP.36  Poster, VCTP47 Date: Thursday, 4 August 2022 Time: 08:30  10:00 Open Kondo circuit as a detector for electronelectron interactions in a Luttinger LiquidT. K. T. Nguyen, A. V. Parafilo, H. Q. Nguyen, and M. N. Kiselev Institute of Physics, Vietnam Academy of Science and Technology, 10 Dao Tan, Hanoi, Vietnam We investigate the effects of the electronelectron (ee) interactions on quantum transport in a one dimensional system. We demonstrate it by considering the model in which a quantum dot is sandwiched between two finite quantum wires or quantum point contacts. We show that the open quantum dot can be used as an ee interaction detector: the temperature scaling of the electric conductance is affected by the interaction in the electron gas through the Luttinger parameter g. Two limits: L<< a and L>>a are considered with L and a are the size of the Luttinger liquid wires and the quantum dot, correspondingly. We also discuss the influence of ee interactions on the nonFermi liquid behavior of the conductance at the two channel Kondo fixed point. Besides, our results bring back the electron interaction independent dc conductance e^2/h in the finite length quantum wires. Presenter: Nguyễn Hồng Quang
