论文摘要
我们探索所有半整数旋转到重力顿的共形初级波函数。半步骤通过超对称性，整数步骤通过经典的双副本相关。主要结果如下：我们1）引入方便的自旋框架和空的四四形，以组织所有不同自旋的辐射模式； 2）识别无质量的自旋 - 3/2保形的一级波功能以及对应于大型超对称转换的形式软金石模式； 3）指出如何以作用于标量初级的差分运算符来表达任意自旋的共形初步； 4）证明，共形初级指标以多种形式满足双重拷贝 - 操作员，Weyl和Kerr-schild-虽然很复杂，但它是petrov型N型完全非线性爱因斯坦方程的解决方案； 5）提出了一个新型的共形初级波函数的概括； 6）表明，这种概括包括一大批与超增强的黑洞，冲击波等相对应的物理有趣的指标。
We explore conformal primary wavefunctions for all half integer spins up to the graviton. Half steps are related by supersymmetry, integer steps by the classical double copy. The main results are as follows: we 1) introduce a convenient spin frame and null tetrad to organize all radiative modes of varying spin; 2) identify the massless spin-3/2 conformal primary wavefunction as well as the conformally soft Goldstone mode corresponding to large supersymmetry transformations; 3) indicate how to express a conformal primary of arbitrary spin in terms of differential operators acting on a scalar primary; 4) demonstrate that conformal primary metrics satisfy the double copy in a variety of forms -- operator, Weyl, and Kerr-Schild -- and are exact, albeit complex, solutions to the fully non-linear Einstein equations of Petrov type N; 5) propose a novel generalization of conformal primary wavefunctions; and 6) show that this generalization includes a large class of physically interesting metrics corresponding to ultra-boosted black holes, shockwaves and more.
