Deformed general relativity
Rhiannon Cuttell
In this thesis, I investigate how to construct a self-consistent model of deformed general relativity using canonical methods and metric variables. The specific deformation of gene…
The general gravitational Lagrangian with deformed covariance
Rhiannon Cuttell, Mairi Sakellariadou
We derive the gravitational Lagrangian to all orders of curvature when the canonical constraint algebra is deformed by a phase space function as predicted by some studies into loop…
The general scalar-tensor Hamiltonian with deformed covariance
Rhiannon Cuttell, Mairi Sakellariadou
We derive the scalar-tensor Hamiltonian constraint to all orders of momenta when the canonical constraint algebra is deformed by a phase space function as predicted by some studies…
Deformed general relativity and scalar-tensor models
Rhiannon Cuttell, Mairi Sakellariadou
We calculate the most general action for a scalar-tensor model up to quadratic order in derivatives with deformed general covariance and non-minimal coupling. We demonstrate how di…
