Boundary CFT spectra, OPE coefficients, and central charges are extracted for normal and ordinary boundaries of the 3D O(2) and O(3) Wilson-Fisher fixed points via fuzzy-sphere state-operator correspondence, with confirmation of positive extraordinary-log exponent alpha.
Bose-Kondo impurities with spins S=1/2, 1, and 3/2 each flow to distinct stable interacting conformal defects despite sharing the same symmetry and anomaly.
Numerical extraction of scaling dimensions and OPE coefficients for 32 primary operators in the O(2) Wilson-Fisher CFT via fuzzy-sphere regularization shows agreement with bootstrap predictions.
