Superadditivity at Large Charge
Timothy Cohen, Ipak Fadakar, Andrew Gomes +2
The weak gravity conjecture has been invoked to conjecture that the dimensions of charged operators in a CFT should obey a superadditivity relation (sometimes referred to as convex…

What is the Geometry of Effective Field Theories?
Timothy Cohen, Xiaochuan Lu, Zhengkang Zhang
We elaborate on a recently proposed geometric framework for scalar effective field theories. Starting from the action, a metric can be identified that enables the construction of g…

On Amplitudes and Field Redefinitions
Timothy Cohen, Xiaochuan Lu, Dave Sutherland
We derive an off-shell recursion relation for correlators that holds at all loop orders. This allows us to prove how generalized amplitudes transform under generic field redefiniti…
