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…
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…
Beyond the Poles in Attractor Models of Inflation
Sotirios Karamitsos
We offer a geometric interpretation of attractor theories with singular kinetic terms as a union of multiple canonical models. We demonstrate that different domains (separated by p…
On the Cosmological Frame Problem
Sotirios Karamitsos, Apostolos Pilaftsis
We introduce a fully-frame covariant formalism for inflation by taking into account conformal transformations in addition to field reparametrizations. We begin by providing a brief…
