我们在d > 2时空维的共形场论中,将共形流形的几何与局部算子的谱联系起来,给出了一系列的图解。我们专注于共形流形的极限点在无限远的Zamolodchikov度量。我们的中心猜想是,所有在无限远距离的理论都具有一种涌现的高自旋对称性,这种对称性是由一个无限大的电流塔产生的,它的反常维度在远处呈指数级消失。从几何学上说,非紧共形流形的直径在高自旋能隙中必须几何发散。在全息背景下,我们的猜想与沼泽地计划中的距离猜想有关。从引力的角度来解释,它们意味着在固定AdS半径的模空间中接近无限远时,一个高自旋场的塔以指数速率变得无质量,该速率从下面以普朗克单位为界。我们讨论了三维和四维超共形场论的共形流形的进一步含义。
We formulate a series of conjectures relating the geometry of conformal manifolds to the spectrum of local operators in conformal field theories in d > 2 spacetime dimensions. We focus on conformal manifolds with limiting points at infinite distance with respect to the Zamolodchikov metric. Our central conjecture is that all theories at infinite distance possess an emergent higher-spin symmetry, generated by an infinite tower of currents whose anomalous dimensions vanish exponentially in the distance. Stated geometrically, the diameter of a non-compact conformal manifold must diverge logarithmically in the higher-spin gap. In the holographic context our conjectures are related to the Distance Conjecture in the swampland program. Interpreted gravitationally, they imply that approaching infinite distance in moduli space at fixed AdS radius, a tower of higher-spin fields becomes massless at an exponential rate that is bounded from below in Planck units. We discuss further implications for conformal manifolds of superconformal field theories in three and four dimensions.
