Cardy猜想与红外强耦合量子场论谱

Cardy's Conjecture and the Spectrum of Infrared Strongly-Coupled Quantum Field Theories

Daniel Davies

摘要:

Cardy关于重整化群(RG)流下迹线异常演化的猜想被重新解释为关于理论的拉格朗日量中的项的标度维数的精确的、非微扰的陈述。当以这种方式看待时,该猜想意味着在红外(IR)中强耦合的场论通常可能具有不表现为紫外(UV)完全理论运动方程的解的状态。特别是,哈密顿算符的标度维度可能会因IR中的$\mathcal{O}(1)$修正而偏离其经典值,从而绕过了德里克关于不存在这种状态\cite{1}的旧论点。我们表明,这个框架提供了一个自然的方法来估计这些国家的质量微扰理论,并建议在IR的自由度的首选重组。

英文摘要:

Cardy's conjecture about the evolution of the trace anomaly under renormalization group (RG) flows is re-interpreted as an exact, non-perturbative statement about the scaling dimension of terms in the Lagrangian of the theory. When viewed in this way, the conjecture implies that field theories which are strongly coupled in the infrared (IR) may generically host states that are not manifest as solutions to the ultraviolet (UV) complete theory's equations of motion. In particular, the scaling dimension of operators in the Hamiltonian may deviate from their classical values by $\mathcal{O}(1)$ corrections in the IR, circumventing an old argument by Derrick about the non-existence of such states\cite{1}. We show that this framework provides a natural way to estimate the masses of these states using perturbation theory, and suggests a preferred reorganization of the degrees of freedom in the IR.
