Spinor driven cosmic bounces and their (in)stability

Shane Farnsworth Max Planck Institute for Gravitational Physics - Albert Einstein Institute (AEI)
Resolving the big bang singularity with a non-singular classical bounce usually requires the introduction of some sort exotic matter which violates the null-energy condition (NEC), such as a scalar field that undergoes ghost condensation, or models involving Galileon fields. In such models an NEC violating phase is not difficult to achieve on its own, but the situation becomes much more restrictive once observational and stability requirements are taken into consideration.
