Quantization and measurability in gauge theory and gravity.
- Schmelzer, Ilja
Considering a mental experiment with a superposition of quasiclassical basic states for gauge theory and gravitation we obtain nonclassical quantum observables. They can be interpreted as the difference of the gauge potentials of the basic states in gauge theory and a homeomorphism of the metrcis of the basic states in general relativity. It is possible to consider gauge- and coordinate conditions (f.e. Lorentz gauge and harmonic coordinates) as new physical equations for these obervables. For gravity we obtain in this way an interesting quasi-classical generalization of general relativity with two times - the time of general relativity and the harmonic time.
