Continuous Family of Conformal Field Theories and Exactly Marginal Operators
Author(s): Shota Komatsu, Yuya Kusuki, Marco Meineri, and Hirosi Ooguri
Does a conformal manifold imply the existence of exactly marginal operators? We answer this question affirmatively under the assumption that there exists a conformal interface with certain properties connecting nearby conformal field theories. We show that the exactly marginal operator that connects… [Phys. Rev. Lett. 136, 241603] Published Tue Jun 16, 2026
