Bulk reconstruction of scalar excitations in Flat3/CCFT2 and the flat limit from (A)dS3/CFT2
A bstract We explore the reconstruction of bulk local states in three-dimensional flat spacetime (Flat 3 ) using states from two-dimensional Carrollian conformal field theories (CCFT 2 ), proposed as dual field theories in one lower dimension. For massive scalar-type bulk excitations, reconstruction is achieved through states in the induced representation. This method successfully reproduces the bulk massive scalar spectrum and the bulk-to-bulk propagator. Additionally, we identify a new flat limit from AdS 3 and dS 3 spacetimes, further validating our proposal for scalar reconstruction in Flat 3 /CCFT 2 .
