论文摘要
我们表明，$ 3D $采购的保形Carrollian田间理论具有正确的运动特性，可以全息描述重力$ 4D $渐变性平时。外部来源编码无效无穷大的重力辐射的泄漏。该理论的病房身份被证明可以在将卡洛利亚人与天体运营商联系起来后重现$ 2D $ CETELSIAL CFT的身份。这表明在渐近平坦的时空，来源的保形卡洛利亚野外理论和天体CFT中，重力之间的一组新相互作用。
We show that a $3d$ sourced conformal Carrollian field theory has the right kinematic properties to holographically describe gravity in $4d$ asymptotically flat spacetime. The external sources encode the leaks of gravitational radiation at null infinity. The Ward identities of this theory are shown to reproduce those of the $2d$ celestial CFT after relating Carrollian to celestial operators. This suggests a new set of interplays between gravity in asymptotically flat spacetime, sourced conformal Carrollian field theory and celestial CFT.
