“…(i) One may recall that in (1+1) dimensions, energy non-conservation is in fact consistent with locality, causality and the long-range character of forces analogous to gravity [13,14]. Even though the reasons for this property are peculiar to (1+1) dimensions, one may wonder whether a similar consistency may be possible in (3 + 1) dimensions.…”

In the framework of a five-dimensional model with one 3-brane and an infinite extra dimension, we discuss a process in which matter escapes from the brane and propagates into the bulk to arbitrarily large distances. An example is a decay of a particle of mass 2m residing on the brane into two particles of mass m that leave the brane and accelerate away. We calculate, in the linearized theory, the metric induced by these particles on the brane. This metric does not obey the four-dimensional Einstein equations and corresponds to a spherical gravity wave propagating along the four-dimensional future light cone. The four-dimensional space-time left behind the spherical wave is flat, so the gravitational field induced in the brane world by matter escaping from the brane disappears in a causal way.

We present the exact solution for the scattering problem in the flat space Jackiw-Teitelboim (JT) gravity coupled to an arbitrary quantum field theory. JT gravity results in a gravitational dressing of field theoretical scattering amplitudes. The exact expression for the dressed S-matrix was previously known as a solvable example of a novel UV asymptotic behavior, dubbed asymptotic fragility. This dressing is equivalent to the TT deformation of the initial quantum field theory. JT gravity coupled to a single massless boson provides a promising action formulation for an integrable approximation to the worldsheet theory of confining strings in 3D gluodynamics. We also derive the dressed S-matrix as a flat space limit of the near AdS 2 holography. We show that in order to preserve the flat space unitarity the conventional Schwarzian dressing of boundary correlators needs to be slightly extended. Finally, we propose a new simple expression for flat space amplitudes of massive particles in terms of correlators of holographic CFT's.

“…Coming back to the present setup as a theory of quantum gravity, one may wonder whether obtaining the exact solution of this simple model may shed light on numerous profound puzzles present in quantum gravity. Indeed, there is a vast body of literature exploring black holes (see, e.g., [19,47]), traversable wormholes [48], baby universes [49] and other beasts in models which appear as rather minimal deformations of the setup studied here.…”
