Loop Quantum Gravity and Cosmology: A dynamical introduction
Martin Bojowald
Loop quantum gravity and cosmology are reviewed with an emphasis on evaluating the dynamics, rather than constructing it. The three crucial parts of such an analysis are (i) derivi…
An effective approach to the problem of time
Martin Bojowald, Philipp A Hoehn, Artur Tsobanjan
A practical way to deal with the problem of time in quantum cosmology and quantum gravity is proposed. The main tool is effective equations, which mainly restrict explicit consider…
Quantum cosmology for the 21st century: A debate
Martin Bojowald, Claus Kiefer, Paulo Vargas Moniz
Quantum cosmology from the late sixties into the early twenty-first century is reviewed and appraised in the form of a debate, set up by two presentations on mainly the Wheeler-DeW…
The high-density regime of kinetic-dominated loop quantum cosmology
Martin Bojowald, David Mulryne, William Nelson +1
We study the dynamics of states perturbatively expanded about a harmonic system of loop quantum cosmology, exhibiting a bounce. In particular, the evolution equations for the first…
Quantum gravity effects on space-time
Martin Bojowald
General relativity promotes space-time to a physical, dynamical object subject to equations of motion. Quantum gravity, accordingly, must provide a quantum framework for space-time…
Spherically Symmetric Quantum Geometry: States and Basic Operators
Martin Bojowald
The kinematical setting of spherically symmetric quantum geometry, derived from the full theory of loop quantum gravity, is developed. This extends previous studies of homogeneous…
