Simplifying general relativity
Speaker(s): Andrew Liddle
Abstract: Modified gravity theories typically feature numerous additional parameters and functions as compared to general relativity, which are unmotivated by observations and challenging to meaningfully constrain. We instead propose a new theory of gravity with the startling property of having *fewer* degree... read more

Random models of inflation
Speaker(s): Andrew Liddle
Abstract: Rather than writing down specific functional forms, one can generate inflation models via stochastic processes in order to explore generic properties of inflation models. I describe our explorations of the phenomenology of randomly-generated multi-field inflation models, both for canonical fields an... read more
