Coherent manipulation of Kondo Majoranas in two-channel Kondo setups
Yashar Komijani, C. J. Bolech
We study coherent manipulation of Majorana zero modes emerging in overscreened two-channel Kondo systems. Using compactified lattice models, we show that these interacting Kondo Ma…
Bosonization solution of the Kondo lattice in a Luttinger liquid
Tomás Bortolin, C. J. Bolech, Nayana Shah +1
We address the physics of a regular arrangement of independent magnetic impurities embedded in a band of interacting electrons. We focus on the one-dimensional case that can be stu…
Kondo destruction quantum critical point: fixed point annihilation and thermodynamic stability
Yiming Wang, Lei Chen, Haoyu Hu +4
A wide range of strongly correlated electron systems exhibit strange metallicity, and they are increasingly recognized as in proximity to correlation-driven localization-delocaliza…
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…
