Dear all,

Speaker Dr Kamal Hajian Affliation Physics school, IPM «تناقض دیوار آتشین» Date and time Wednesday, 14th of Bahman (3rd of February), 4:30 pm Place Farmanieh, Lecture room C Abstract Black hole information paradox has been a concomitant of realizing these
objects/solutions as thermodynamic systems. The paradox can be
explained as: in the semi-classical regime which gravity is dealt
classically, black hole evaporation is not a unitary process. A famous
resolution to this paradox was presented in 1993, which is called
``black hole complementarity". This resolution can be roughly explained
as: the set of observers standing outside of the black hole and the set
of observers falling freely into it should be considered complement to
each other. One can not see the world from the point of view of both
sets of observers. Using this complementarity, the information paradox
has been considered to be resolved. But, according to recent
investigations, it has been shown that black hole complimentarity yields
another paradox which is known as ``firewall paradox". In this talk, we
will review this paradox and some resolutions to it. |
