Résumé |
The black hole complementarity principle states that reasonable postulates such as
semi-classicality and unitarity of the evaporation process imply that information
is both inside and outside the black hole, but no observer can access both copies.
More recently. It has been pointed out that the apparently reasonable postulates
supporting this principle contradicts strong subadditivity of tripartite
entanglement between the early and late radiation, and the modes in the interior.
Although there has been a lot of discussion in the literature about how the
complementarity principle can be saved from clutches of paradoxes, we know very
little of how it can emerge explicitly from microscopic dynamics without
contradicting basic properties of von Neumann algebras. In this talk, we will
present a simplified version of a black hole microstate model, where we can
explicitly demonstrate replication of information via interaction between
infalling quantum matter and the black hole interior, in consistency with von
Neumann algebras. We will also discuss setups where more details of encoding of
initial information into black hole interior and its subsequent transfer to
Hawking radiation can be studied explicitly, and as a first example, discuss
explicit information mirroring which satisfies additional requirements imposed by
the complementarity principle. |
