Carrollian correlators in black hole perturbation theory
Jiang Long, Zhan-Jia Qu, Hong-Yang Xiao
In this note, we clarify the relationship between the two-point Carrollian correlator and massless scattering in black hole background. It turns out that there are two kinds of Car…

Thermal correlator at null infinity
Jiang Long, Hong-Yang Xiao
We study the thermal Carrollian correlators at null infinity in the real-time formalism. We derive the Feynman rules to calculate these correlators in the position space. We comput…

On the definition of Carrollian amplitudes in general dimensions
Wen-Bin Liu, Jiang Long, Hong-Yang Xiao +1
Carrollian amplitude is the natural object that defines the correlator of the boundary Carrollian field theory. In this work, we will elaborate on its proper definition in general…
