Quantum communication through a partially reflecting accelerating mirror [PDF]
, 2021 Motivated by the fact that the null shell of a collapsing black hole can be described by a perfectly reflecting accelerating mirror, we investigate an extension of this model to mirror semitransparency and derive a general implicit expression for the ...
