基于量子码的模自举约束求解

Solutions of modular bootstrap constraints from quantum codes

Anatoly Dymarsky, Alfred Shapere

摘要:

模不变性对二维共形场论的配分函数施加了严格的约束。许多基本结果严格遵循模不变性,从而产生了数值模引导程序。在这里,我们报告了一种方法来分配给一个特定的家庭的量子纠错码的“代码CFTs”CFTs的家庭,它形成了一个子集的Narain CFTs空间。这种对应关系将2d CFT配分函数的模不变性减少到由表征对应代码的多元多项式服从的几个简单代数关系。使用这种关系,我们构建了许多明确的例子,物理上不同的等谱理论,以及许多例子的nonholomorphic函数,满足所有的基本性质的二维CFT配分函数,但没有与任何已知的CFT。

英文摘要:

Modular invariance imposes rigid constrains on the partition functions of two-dimensional conformal field theories. Many fundamental results follow strictly from modular invariance, giving rise to the numerical modular bootstrap program. Here we report a way to assign to a particular family of quantum error correcting codes a family of "code CFTs" CFTs", which forms a subset of the space of Narain CFTs. This correspondence reduces modular invariance of the 2d CFT partition function to a few simple algebraic relations obeyed by a multivariate polynomial characterizing the corresponding code. Using this relation we construct many explicit examples of physically distinct isospectral theories, as well as many examples of nonholomorphic functions, which satisfy all basic properties of the 2d CFT partition function, yet are not associated with any known CFT.
