POSSIBLE UNITARITY OF BLACK HOLE EVAPORATION
2019.10.29 14:11 - Anna RędaszekIn the framework of finite-dimensional Fock space models, for a fixed given mean number of particles $\bar{n}_{k}$, blackbody-like or another, it is shown that there are, in the space $S$ of all pure states, a multi-dimensional subspace $s_{\bar{n}_{k}}$ of initial pure states and a corresponding multi-dimensional subspace $S_{\bar{n}_{k}}$ of final pure states yielding $\bar{n}_{k}$, which are mutually related by a unitary transformation.
