DESCRIPTION:Title: <a href="https://researchseminars.org/talk/RENC-THEO/5/
 ">Quantum codes\, lattices\, and conformal field theories</a>\nby Anatoly 
 Dymarsky (U. Kentucky & Skoltech) as part of Rencontres Théoriciennes\n\n
 Lecture held in online only.\n\nAbstract\nThere is a deep relation between
  classical error-correcting\ncodes\, Euclidean lattices\, and chiral 2d CF
 Ts. We show this relation\nextends to include quantum codes\, Lorentzian l
 attices\, and non-chiral\nCFTs. The relation to quantum codes provides a s
 imple way to solve\nmodular bootstrap constraints and identify interesting
  examples of\nconformal theories. In particular we construct many examples
  of\nphysically distinct isospectral theories\, examples of "would-be" CFT
 \npartition function -- non-holomorphic functions satisfying all\nconstrai
 nts of the modular bootstrap\, yet not associated with any\nknown CFT\, an
 d find theory with the maximal spectral gap among all\nNarain CFTs with th
 e central charge c=4. We also discuss averaging\nover the ensemble of all 
 CFTs associated with quantum codes\, and its\npossible holographic interpr
 etation. The talk is based on\narXiv:2009.01236 and arXiv:2009.01244.\n
