Asymptotic Fock spaces lead to IR divergences in S-matrices. The issue can be traced back to the assumption of asymptotic decoupling, and its relaxation leads to Faddeev-Kulish states and an IR-finite S-matrix. In this paper we initiate the exploration of these states in the context of the flat limit of AdS/CFT. We construct asymptotic states as flat limits of fields that interact with the electro-magnetic field in AdS, and provide a reconstruction in terms of the dual CFT operators.

Li\'enard--Wiechert fields in AdS and flat-space antipodal matching from geodesic-centered Coulombic data
Liénard–Wiechert fields and flat-space antipodal matching arise by expressing a static Coulomb seed in geodesic-centered coordinates, with exact bulk antipodal covariance in AdS reducing to the usual matching at null fringes.

Li\'enard--Wiechert fields in AdS and flat-space antipodal matching from geodesic-centered Coulombic data
The Coulombic Liénard–Wiechert field in AdS and flat space is obtained by recentering the static Coulomb seed on the source geodesic, and antipodal matching emerges as the flat-space limit of an exact bulk antipodal c...

Li\'enard--Wiechert fields in AdS and flat-space antipodal matching from geodesic-centered Coulombic data
A uniformly moving charge's field is a static Coulomb field in geodesic-centered coordinates, and in AdS the same construction yields a closed-form field with exact antipodal covariance whose null-fringe limits give f...

Nonperfect Carrollian Fluids Through Holography
Bulk gravitational radiation, diagnosed by the Fernández-Álvarez–Senovilla criterion, is dual to dissipative (Carrollian) boundary-fluid data, with an entropy-flux law and a Robinson-Trautman worked example.
