Titre | Information loss and black holes, or how to read the Page curve |
Résumé | Information may or may not be lost in black hole evaporation. I will discuss possible physical consequences of this alternative from the perspective of asymptotic observers away from the hole. To this aim, I will describe the relationship between radiated energy and entanglement entropy of massless fields at future null infinity (the "Page curve") in two-dimensional models of gravitational collapse and subsequent black hole evaporation. I will then use this framework to show that, if information is preserved and backscattering can be neglected, then (i) the mass of the hole cannot decrease monotonically, and (ii) purification cannot be fast/burst-like. I will discuss some recent proposals for nonsingular evaporation in light of these results. |
