Schwinger-Keldysh effective theory of charge transport: redundancies and systematic expansion
Eren Firat, Andrew Gomes, Filippo Nardi +2
We study Schwinger-Keldysh effective field theories (EFTs) for systems with non-Abelian internal symmetries near thermal equilibrium. We consider two approaches that were put forwa…

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…
