Deformed Density Matrix and Quantum Entropy of the Black Hole
In the present work the approach-density matrix deformation-earlier developed by the author to study a quantum theory of the Early Universe (Planck's scales) is applied to study a quantum theory of black holes. On this basis the author investigates the information paradox problem, entropy of the black hole remainders after evaporation, and consistency with the holographic principle. The possibi...
متن کاملInformation in black hole radiation.
If black hole formation and evaporation can be described by an S matrix, information would be expected to come out in black hole radiation. An estimate shows that it may come out initially so slowly, or else be so spread out, that it would never show up in an analysis perturbative in MP lanck/M , or in 1/N for two-dimensional dilatonic black holes with a large number N of minimally coupled scal...
متن کاملA Matrix-Model Black Hole
In this paper the c = 1 matrix model deformed by a 1/x piece is discussed. Tachyon correlation functions are calculated up to genus two using methods similar to those for the undeformed case. The possible connection with the two dimensional black hole is also considered. In particular, restrictions on naked singularities imposed by the matrix model are found. CERN-TH.6916/93 June 1993
متن کاملThe sonic analogue of black hole radiation
A microscopic description of Hawking radiation in sonic black holes has been recently presented [1]. This exactly solvable model is formulated in terms of onedimensional scattering of a Fermi gas. In this paper, the model is extended to account possible finite size effects of a realistic geometry. The flow of particles is maintained by a piston (i.e. an impenetrable barrier) moving slowly towar...
متن کاملProperties of Black Hole Radiation from Tunnelling
We consider the space-time associated with the evaporation of a black hole by quantum mechanical tunnelling events. It is shown that the surface through which tunnelling occurs is distinct from the global event horizon, and that this has consequences for the radiation reaching future null infinity.
