Today's #arXivsummary: https://arxiv.org/abs/2302.07883 by Han et. al. Authors study the effect of electron-electron interactions on the non-Hermitian Kondo problem in a Luttinger liquid. Perturbative renormalization group analysis to two-loop order illustrates that the interplay between non-Hermitian Kondo couplings and electron-electron interactions may produce a pair of complex fixed points. #CondMat #StrEl #arXiv_2302_07883
