Bosonization Solution to Spin-Valley Kondo Problem: Finite-Size Spectrum and Renormalization Group Analysis
Yi-Jie Wang, Geng-Dong Zhou, Hyunsung Jung +3
Spin-valley Anderson impurities (SVAIM) with (anti-)Hund's splitting provide a natural explanation to the origin of pairing potential and pseudogap in the magic-angle graphene. In…

Spin-Valley Anderson Impurity for Moiré Systems: Fermi Liquid, Pairing, and Pseudogap
Yi-Jie Wang, Geng-Dong Zhou, Hyunsung Jung +3
Recent experiments support that the magic-angle graphene can be modeled by a periodic array of correlated quantum impurities, immersed in a Dirac sea. This work analytically tackle…
