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…
Spin fractionalization in a Kondo-lattice superconductor heterostructure
Ethan Huecker, Yashar Komijani
Kondo lattices are one of the classic models of strongly correlated systems where despite a long history, a full understanding of the excitation spectra is still not available. Her…
Dynamic mass generation and topological order in overscreened Kondo lattices
Yang Ge, Yashar Komijani
Multichannel Kondo lattice models are examples of strongly correlated electronic systems that exhibit non-Fermi-liquid behavior due to the presence of a continuous channel symmetry…
Towards Entanglement Entropy of Random Large-N Theories
Siqi Shao, Yashar Komijani
A large class of strongly correlated quantum systems can be described in certain large-N limits by quadratic in field actions along with self-consistency equations that determine t…
