Higher-Dimensional Chirally Stabilized Fixed Points and Their Deformations
Aleksandar Ljepoja, L. C. R. Wijewardhana, Yashar Komijani
Non-Fermi liquids in remain poorly understood, particularly when relevant perturbations destabilize them. In one spatial dimension, chirally stabilized fixed points provide a…
Topological ground state degeneracy of the two-channel Kondo lattice
Aleksandar Ljepoja, Yashar Komijani
There are indications from the large-N analysis that multi-channel Kondo lattices have topological order. We use the coupled-wire construction to study the channel paramagnetic reg…
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…
