Bose-Einstein condensed supermassive black holes: a case of renormalized quantum field theory in curved space-time

Popis výsledku v původním jazyce

This paper investigates the question whether a realistic black hole can be in principal similar to a star, having a large but finite redshift at its horizon. If matter spreads throughout the interior of a supermassive black hole with mass M similar to 10(9)M(circle dot), it has an average density comparable to air and it may arise from a Bose-Einstein condensate of densely packed H-atoms. Within the Relativistic Theory of Gravitation with a positive cosmological constant, a bosonic quantum field describing H atoms is coupled to the curvature scalar with dimensionless coupling xi. In the Bose-Einstein condensed groundstate ail exact, self-consistent solution for the metric occurs for a certain large value of, quadratic in the black hole mass. It is putforward that xi is set by proper choice of the background metric as a first step of a renormalization approach, while otherwise the non-linearities are small. The black hole has a hair, the binding energy. Fluctuations about the ground st
