Conformal Scalar Field Theory from Ising Tricriticality on the Fuzzy Sphere

Author(s): Joseph Taylor, Cristian Voinea, Zlatko Papić, and Ruihua Fan Free theories are landmarks in the landscape of quantum field theories: their exact solvability serves as a pillar for perturbative constructions of interacting theories. Fuzzy sphere regularization, which combines quantum Hall physics with state-operator correspondence, has recently been proposed a… [Phys. Rev. Lett. 136, 056503] Published Fri Feb 06, 2026
