Geometrising the Micro-Cosmos on a Supermanifold
Kieran Finn, Viola Gattus, Sotirios Karamitsos +1
For more than half a century, covariant and differential geometric methods have been playing a central role in the development of Quantum Field Theory (QFT). After a brief historic…
Quantizing the Eisenhart Lift
Kieran Finn, Sotirios Karamitsos, Apostolos Pilaftsis
The classical Eisenhart lift is a method by which the dynamics of a classical system subject to a potential can be recreated by means of a free system evolving in a higher-dimensio…
Initial Conditions of Inflation in a Bianchi I Universe
Kieran Finn
We investigate the initial conditions of inflation in a Bianchi~I universe that is homogeneous but not isotropic. We use the Eisenhart lift to describe such a theory geometrically…
Frame Covariance in Quantum Gravity
Kieran Finn, Sotirios Karamitsos, Apostolos Pilaftsis
We develop a quantum effective action for scalar-tensor theories of gravity which is both spacetime diffeomorphism invariant and field reparameterisation (frame) invariant beyond t…
A Finite Measure for the Initial Conditions of Inflation
Kieran Finn, Sotirios Karamitsos
We investigate whether inflation requires finely tuned initial conditions in order to explain the degree of flatness and homogeneity observed in the Universe. We achieve this by us…
The Eisenhart Lift for Field Theories
Kieran Finn, Sotirios Karamitsos, Apostolos Pilaftsis
We present the Eisenhart-lift formalism in which the dynamics of a system that evolves under the influence of a conservative force is equivalent to that of a free system embedded i…
