Anotácia knihy

Canonical gravity in real Ashtekar--Barbero §variables is generalized§ by extending Holst's original vacuum analysis to §allow for both fermionic and bosonic matter. For §fermions, the effects of emerging torsion on parity §and the known§ canonical (loop) quantization of gravity§ are discussed on the basis of the classical §analysis by eliciting the necessity for adaptations. §Then the role of these matter fields in homogeneous §models of loop quantum cosmology is explored by §discussing their influence on the behavior of the §Wheeler-deWitt equation for the wave function of the §universe. Next, quantum gravity corrections to §equation of state parameters for Maxwell and Dirac §fields arising from the discrete geometry of loop §quantization are computed to investigate its effect §on Big Bang Nucleosynthesis (BBN) to place bounds on §these corrections and especially the patch size of §discrete quantum gravity states. Finally, an example §of the effects of these corrected equation of state §on the evolution of dark energy, in particular k-§essence and quintessence, is presented.
