Solving the flatness problem with an anisotropic instanton in Hořava-Lifshitz gravity
Sebastian F. Bramberger, Andrew Coates, João Magueijo +3
In Hořava-Lifshitz gravity a scaling isotropic in space but anisotropic in spacetime, often called anisotropic scaling with the dynamical critical exponent z=3, lies at the base of…
The Wavefunction of Anisotropic Inflationary Universes With No-Boundary Conditions
Sebastian F. Bramberger, Shane Farnsworth, Jean-Luc Lehners
We study the emergence of anisotropic (Bianchi IX) inflationary universes with no-boundary conditions in the path integral approach to quantum gravity. In contrast to previous work…
Quantum Transitions Through Cosmological Singularities
Sebastian F. Bramberger, Thomas Hertog, Jean-Luc Lehners +1
In a quantum theory of cosmology spacetime behaves classically only in limited patches of the configuration space on which the wave function of the universe is defined. Quantum tra…
