A solvable model of flat space holography
We propose an explicit realization of flat space holography in two dimensions where both sides of the duality are independently defined and the...

Towards higher-spin holography in flat space
We study the chiral flat space higher-spin algebra, which is the global symmetry algebra of the chiral higher-spin theory in the 4d Minkowski space....

An embedding space approach to Carrollian CFT correlators for flat space holography
Carrollian conformal field theories (carrollian CFTs) are natural field theories on null infinity of an asymptotically flat spacetime or, more...

Flat holography and celestial shockwaves
In this paper we systematically develop the flat/CFT holographic dictionary, building on AdS/CFT holography. After analysing the behaviour of scalar...

Chiral higher-spin holography in flat space: the Flato-Fronsdal theorem and lower-point functions
We prove the flat space analogue of the Flato-Fronsdal theorem. It features the flat space singleton representation suggested recently. We do that by...

Bulk reconstruction in flat holography
In this note, we discuss the bulk reconstruction of massless free fields in flat space from the highest-weight representation of boundary Carrollian...

Carrollian approach to 1 + 3D flat holography
The isomorphism between the (extended) BMS 4 algebra and the 1 + 2D Carrollian conformal algebra hints towards a co-dimension one formalism of flat...

Burns space and holography
We elaborate on various aspects of our top-down celestial holographic duality wherein the semiclassical bulk spacetime is a 4d asymptotically flat,...

Aspects of higher spin symmetry in flat space
We review some aspects of higher spin symmetry, in (Anti-)de Sitter and flat space–times, aiming at closing the gap between the constantly curved and...

Mixed boundary conditions and double-trace like deformations in Celestial holography and Wedge-like holography
According to the AdS/CFT dictionary, adding a relevant double-trace deformation f ∫ O 2 to a holographic CFT action is dual to imposing mixed...

Holography of information in de Sitter space
We study the natural norm on the space of solutions to the Wheeler-DeWitt equation in an asymptotically de Sitter spacetime. We propose that the norm...

A generalized Selberg zeta function for flat space cosmologies
Flat space cosmologies (FSCs) are time dependent solutions of three-dimensional (3D) gravity with a vanishing cosmological constant. They can be...

Celestial holography from chiral strings
In this paper, we studied the relationship between celestial holography and chiral strings. Chiral strings differ from the usual string theory by a...

Holography of information in massive gravity using Dirac brackets
The principle of holography of information states that in massless gravity, it is possible to extract bulk information using asymptotic boundary...

A Matrix Model for Flat Space Quantum Gravity
We take a step towards the non-perturbative description of a two-dimensional dilaton-gravity theory which has a vanishing cosmological constant and...

Flat space holography in spin-2 extended dilaton-gravity
We present an interacting spin-2 gauge theory coupled to the two-dimensional dilaton-gravity in flat spacetime. The asymptotic symmetry group is...

\(w_{1+\infty }\) and Celestial Holography
In recent years, there has been a resurgence in the search for holographic dualities in asymptotically flat space-times (cf., Strominger A in...

Computer Generated Holography
Computational holography combines traditional optical imaging with computational techniques, which can improve the capabilities of a camera, and...
