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…

Geometry of soft scalars at one loop
Timothy Cohen, Ipak Fadakar, Andreas Helset +1
We extend the soft theorems for scattering amplitudes of scalar effective field theories to one-loop order. Our analysis requires carefully accounting for the fact that the soft li…

Tetraquarks at large and large
Héloïse Allaman, Majid Ekhterachian, Filippo Nardi +2
We study tetraquarks in large QCD with heavy quarks, in the domain where non-relativistic quantum mechanics offers an adequate approximation. Within the regime of validity of t…
