Quantum gravity as a unified theory coupled to quantized matter fields. Abstract In this paper we place some results of previous works together into a larger overall context. First we quantize the gravity-matter system in Ashtekar variables as a unified field, combining the Dirac, reduced phase space, geometric and path integration approaches, and construct the generalized Kodama state by expan...

We consider an approach in which the usual wave function quadrature representation of mode j electromagnetic field is further quantized to produce a operator. Since already second quantized, this corresponds additional or third quantization. The third-quantization can be used perform certain quantum optics calculations Heisenberg picture that could only performed Schrodinger when using conventi...
