Systematic compactification of the two-channel Kondo model. III. Extended field-theoretic renormalization group analysis
Aleksandar Ljepoja, C. J. Bolech, Nayana Shah
We carry out a field-theoretical renormalization group procedure based on the Callan-Symanzik equation to calculate the detailed flow for the (multi) two-channel Kondo model and it…

Systematic compactification of the two-channel Kondo model. II. Comparative study of scaling and universality
Aleksandar Ljepoja, Nayana Shah, C. J. Bolech
Following up on the systematic compactification of the two-channel Kondo model (and its multichannel extensions; arXiv:2308.03569 (companion paper I)) and the demonstration of its…

Systematic compactification of the two-channel Kondo model. I. Consistent bosonization-debosonization approach and exact comparisons
Aleksandar Ljepoja, C. J. Bolech, Nayana Shah
Capitalizing on recent work, that clarifies the consistent use of bosonization-debosonization methods to study Kondo-type quantum impurity models even in nonequilibrium settings, w…
