Anisotropic Spinfoam Cosmology

Understand

The dynamics of a homogeneous, anisotropic universe are investigated within the context of spinfoam cosmology.

• Transition amplitudes are calculated for a graph consisting of a single node and three links - the `Daisy graph' - probing the behaviour a classical Bianchi I spacetime.
• It is shown further how the use of such single node graphs gives rise to a simplification of states such that all orders in the spin expansion can be calculated, indicating that it is the vertex expansion that contains information about quantum dynamics.
