PhD position in bouncing cosmology, Nottingham, UK

This PhD project is mainly devoted to the study of cosmological inhomogeneities in two different “bounce” scenarios, in which the classical Big Bang singularity is resolved by quantum effects. The first of these scenarios describes the Universe as a “condensate” of a large number of quantum atoms of geometry within the group field theory approach to quantum gravity. The second scenario uses symmetry-reduced models with in which the Universe can make a quantum transition from a contracting to an expanding phase. The project will study cosmological perturbations within these two bounce models, explore potential observational signatures, and focus on the connection to other bounce scenarios and formalisms for quantum cosmology, such as loop quantum cosmology or the no-boundary proposal for quantum cosmology.

The PhD studentship is associated to the Royal Society University Research Fellowship project “Addressing the Big Bang singularity in quantum gravity and quantum cosmology” by Dr Steffen Gielen.

We are looking for an enthusiastic applicant with a first class degree in Theoretical/Mathematical Physics or equivalent (strong mathematical background is essential), preferably at MSc/MMath level, or equivalent non-UK degree. Candidates with a 2:1 degree can be considered in exceptional cases. Prior research experience in quantum cosmology or cosmological perturbation theory would be an advantage, but is not essential.

The studentship is for four years, and covers tuition fees at the Home/EU rate as well as a stipend of currently £14,553 per year.

Starting date can be October 2018 or earlier; the position will be open until filled.
Review of applications will begin shortly, so early application is strongly recommended. Please write to the email address above if you are interested in applying.
