Area / Radiation Spectrum {& V Mukhanov, GE seminar 24.11.1995.}
* Discrete, equal spacing:
(Bekenstein & Mukhanov) A = 4
ln 2, where n is a principal quantum no, of degeneracy
=
2 n–1 (from S
ln
and S = A/4),
so M
n1/2;
Lifetime of a level
3840
–1 M ln2,
1;
(Hod) A = 4n
/ln3;
This kind of
spectrum is not consistent with loop quantum gravity.

Radiation, Evaporating Black Holes > s.a. black
hole radiation.
* Remark: The results
from semiclassical gravity are indicative of an important feature of full quantum
gravity, and of a deep connection between quantum field theory, quantum gravity
and thermodynamics,
not yet understood; 1990, In particular, it is not clear whether a horizon
will form
in full quantum gravity as in the semiclassical theory, and where the radiation
comes from physically.
* Spectrum: A line spectrum
arises from transition between states, whose envelope is a (truncated) thermal
spectrum; Line width
E
–1
1/30
of the line spacing; The spectrum is truncated because quanta
that spend a long time near the horizon feel its quantum fluctuations.
* Rad and cutoffs: Radiation
seems not to be present if one puts a "hard" length
cutoff, but survives a "soft" one.
