Quantum dot in a two-dimensional topological insulator: The two-channel Kondo fixed point
A quantum dot coupled to two helical edge states of a two-dimensional topological insulator through electron tunnelings is studied. We show that if the electron interactions on the edge states are repulsive, with Luttinger liquid parameter K<1, the system reaches a stable two-channel Kondo fixe...
