Pre-Holography

TL;DR

This paper constructs a symplectic isomorphism linking classical Klein Gordon solutions in Anti de Sitter space to boundary functions, providing new insights into holography and boundary dualities in quantum field theory.

Contribution

It introduces a symplectic isomorphism for Klein Gordon solutions in AdS, establishing a new class of algebraic holography examples and clarifying boundary-limit holography conditions.

Findings

Established a symplectic isomorphism h for Klein Gordon solutions in AdS.

Mapped local quantum Klein Gordon algebras in AdS to boundary conformal field algebras.

Showed boundary-limit holography as a quantum duality under specific test function restrictions.

Abstract

We construct a symplectic isomorphism, h, from classical Klein Gordon solutions of mass m on (d+1)-dimensional Lorentzian Anti de Sitter space (equipped with the usual symplectic form) to a certain symplectic space of functions on its conformal boundary (only) for all integer and half-integer Delta (= d/2 + (1/2)(d^2 + 4m^2)^{1/2}). h induces a large family of new examples of Rehren's algebraic holography in which the net of local quantum Klein Gordon algebras in AdS is seen to map to a suitably defined net of local algebras for the (generalized free) scalar conformal field with anomalous dimension Delta on d-dimensional Minkowski space (the AdS boundary). Relatedly, we show for these models that Bertola et al's boundary-limit holography becomes a quantum duality (only) if the test functions for boundary Wightman distributions are restricted in a particular way.
