Origin of time and probability in quantum cosmology
Leonardo Chataignier, Claus Kiefer, Mritunjay Tyagi
We discuss how the classical notions of time and causal structure may emerge together with quantum-mechanical probabilities from a universal quantum state. For this, the process of…
Time and its arrow from quantum geometrodynamics?
Claus Kiefer, Leonardo Chataignier, Mritunjay Tyagi
We discuss how quantum geometrodynamics, a conservative approach to quantum gravity, might explain the emergence of classical spacetime and, with it, the emergence of classical tim…
Quantum Gravitational Collapse in the Lemaitre-Tolman-Bondi Model with a Positive Cosmological Constant
Anne Franzen, Sashideep Gutti, Claus Kiefer
Previous papers dealt with the quantization of the Lemaitre-Tolman-Bondi (LTB) model for vanishing cosmological constant . Here we extend the analysis to the case . Our mai…
