State-Operator Correspondence in Celestial Conformal Field Theory
Erin Crawley, Noah Miller, Sruthi A. Narayanan +1
The bulk-to-boundary dictionary for 4D celestial holography is given a new entry defining 2D boundary states living on oriented circles on the celestial sphere. The states are cons…
Massive Celestial Fermions
Sruthi A. Narayanan
In an effort to further the study of amplitudes in the celestial CFT (CCFT), we construct conformal primary wavefunctions for massive fermions. Upon explicitly calculating the wave…
The Soft -Matrix in Gravity
Elizabeth Himwich, Sruthi A. Narayanan, Monica Pate +2
The gravitational -matrix defined with an infrared (IR) cutoff factorizes into hard and soft factors. The soft factor is universal and contains all the IR and collinea…
Uplifting AdS3/CFT2 to Flat Space Holography
Adam Ball, Elizabeth Himwich, Sruthi A. Narayanan +2
Four-dimensional (4D) flat Minkowski space admits a foliation by hyperbolic slices. Euclidean AdS3 slices fill the past and future lightcones of the origin, while dS3 slices fill t…
