SpaceTime Foliation in Quantum Gravity, by Yuki Sato, (electronic resource)
 Summary
 In this thesis, the author considers quantum gravity to investigate the mysterious origin of our universe and its mechanisms. He and his collaborators have greatly improved the analyticity of two models: causal dynamical triangulations (CDT) and nDBI gravity, with the spacetime foliation which is one common factor shared by these two separate models.   In the first part, the analytic method of coupling matters to CDT in 2dimensional toy models is proposed to uncover the underlying mechanisms of the universe and to remove ambiguities remaining in CDT. As a result, the wave function of the 2dimensional universe where matters are coupled is derived. The behavior of the wave function reveals that the Hausdorff dimension can be changed when the matter is nonunitary.   In the second part, the nDBI gravity model is considered. The author mainly investigates two effects driven by the spacetime foliation: the appearance of a new conserved charge in black holes and an extra scalar mode of the graviton. The former implies a breakdown of the blackhole uniqueness theorem while the latter does not show any pathological behavior
