Semiclassical Quantum Cosmology |
In General
> s.a. quantum cosmology [decoherence, effective Hamiltonian and dynamics];
semiclassical quantum gravity [continuum limit].
* Idea: The sector of a quantum theory
of gravity containing states with a semiclassical interpretation as cosmological models
of spacetime–this is different from semiclassical gravity in a cosmological spacetime.
