a Two-channel Kondo (2CK) phase diagram. It consists of the local moment (LM), single-channel Kondo (1CK), and two-channel Kondo (2CK) phases. δJ is the channel anisotropy, T is the temperature, TK is the Kondo temperature, and T * is the crossover temperature. b Cloud distribution at a point marked by the red star in the 1CK domain of the phase diagram of a. The coupling strengths are J1 = J + δJ and J2 = J − δJ. The cloud distribution has the core, 1CK, 2CK and non-Kondo Fermi liquid (FL) shells. ξK is the Kondo length and ξ * is the crossover length. c, d Log–log plots of the distribution ρi(L) in channel i = 1, 2 at zero temperature. Cloud shells are identified by their power-law decay. e Ratio ρ2/ρ1 at L ≫ ξ *. Here, ν is the local density of states. The numerical renormalization group (NRG) results (dots) agree with the bosonization prediction (solid curve).
