Phenomenology |
In General > s.a. geodesics;
spacetime [measurement]; kaluza-klein
theory; variation of constants.
* Possibilities: Particle
spectra, or effects on microscopic spacetime quantum geometry, which in turn
affect particle propagation (> see quantum
gravity phenomenology);
Space and time variation of the effective G (> see gravitational
constant).

Cosmology > s.a. chaos
in the metric and
bianchi models; cosmological
constant; inflation.
* Idea: Higher-dimensional
cosmology; most models are anisotropic and generalize the Kasner and the Mixmaster
universes.
* Features: Casimir effects
lead to spontaneous compactification.

Compactification > s.a. Pyrgon;
spacetime models [dimensional reduction].
* Idea: In traditional
Kaluza-Klein models, one usually wants a compact internal manifold (usually
a coset space), of size of the order of Planck length; This usually
involves matter fields, and the gravitational Casimir effect to fix an
equilibrium
internal size; More recent proposals have used either non-compact,
or compact
but large internal dimensions (> see branes).
* Spontaneous compactification:
One introduces a potential Aabc
which contributes –(1/48) Fabcd Fabcd to
the Lagrangian, where F:=
dA;
The v.e.v. of F drives the spontaneous compactification.
* Remark: One wants a particular kind of energy-momentum density matter
condensate in the quantized ground state, or of spin-density matter condensate
(only for
parallelizable fibers).
