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…
Conformal Collider Physics at Large Charge
Gabriel Cuomo, Eren Firat, Filippo Nardi +1
We study energy correlators and other event shapes in states created by operators with large global charge in Conformal Field Theories. Focusing on theories whose large…
Quantum vorticity: a not so effective field theory
Gabriel Cuomo, Fanny Eustachon, Eren Firat +2
We provide a comprehensive picture for the formulation of the perfect fluid in the modern effective field theory formalism at both the classical and quantum level. Due to the neces…
Flux Correlators and Semiclassics
Eren Firat, Alexander Monin, Riccardo Rattazzi +1
We consider correlators for the flux of energy and charge in the background of operators with large global charge in conformal field theory (CFT). It has recently been shown…
