Tabletop Analog Black Holes to Investigate Information Loss Paradox
The question of whether Hawking evaporation violates unitarity, and therefore results in the loss of information, has remained unresolved since Hawking’s seminal discovery. To date, the investigations have remained mostly theoretical since it is almost impossible to settle this paradox through direct astrophysical black hole observations. In this talk we will review the problem and the various solutions to the information paradox. We will then argue for the necessity of investigating analog black holes. Recently we pointed out that relativistic flying plasma mirrors can be accelerated drastically and stopped abruptly by impinging intense x-ray pulses on solid plasma targets with a density gradient. This is analogous to the late time evolution of black hole Hawking evaporation. It is hoped that such investigation can help to shed more lights on the information loss paradox.
