天体全息照相的卡罗里观点

Carrollian Perspective on Celestial Holography

Laura Donnay, Adrien Fiorucci, Yannick Herfray, Romain Ruzziconi

摘要:

我们证明了$3d$来源的共形卡罗场论具有正确的运动学性质来全息描述$4d$渐近平坦时空中的引力。外部源编码了零无穷远处的引力辐射泄漏。这个理论的沃德恒等式再现那些$2d$天体CFT后,有关的Carrollian天体运营商。这暗示了在渐近平坦时空中引力之间的一系列新的相互作用,来源于共形卡罗场论和天体CFT。

英文摘要:

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.
