摘要

We investigate the reconstruction of bulk local states in flat spacetime using states from Carrollian conformal field theories (CCFTs), which are proposed as the dual field theories in one dimension lower for flat holography. For scalar-type massive excitations in the bulk, the reconstruction can be achieved through states in what is known as the induced representation. In this scenario, we observe a match between the Hilbert spaces of the bulk and the boundary. Additionally, the bulk flat correlation functions can be reproduced using the induced states in the boundary field theories. In this talk, I will briefly review the flat spacetime holography and Carrollian conformal field theories and then go to the bulk reconstruction.
