3 0 A ug 2 00 7 A universal constraint between charge and rotation rate for degenerate black holes surrounded by matter

چکیده
We consider stationary, axially and equatorially symmetric systems consisting of a central rotating and charged degenerate black hole and surrounding physically realistic matter. We show that a + Q = M always holds, where a = J/M is the black hole’s intrinsic angular momentum per unit mass, Q its electric charge and M the well known black hole mass parameter introduced by Christodoulou and Ruffini.

We consider stationary, axially and equatorially symmetric systems consisting of a central rotating and charged degenerate black hole and surrounding matter. We show that a + Q = M always holds provided that a continuous sequence of spacetimes can be identified, leading from the Kerr-Newman solution in electrovacuum to the solution in question. The quantity a = J/M is the black hole’s intrinsic...

We show that there is a close correspondence between the physical properties of holographic metals near charged black holes in anti-de Sitter (AdS) space, and the fractionalized Fermi liquid phase of the lattice Anderson model. The latter phase has a ‘small’ Fermi surface of conduction electrons, along with a spin liquid of local moments. This correspondence implies that certain mean-field gapl...

The most massive black holes, lurking at the centers of large galaxies, must have formed less than a billion years after the big bang, as they are visible today in the form of bright quasars at redshift larger than six. Their early appearance is mysterious, because the radiation pressure, generated by infalling ionized matter, inhibits the rapid growth of these black holes from stellar-mass bla...
