Schwinger-Keldysh effective actions for non-hydrodynamic poles and branch cuts
Andrea Amoretti, Matteo Anselmi, Daniel K. Brattan
Retarded thermal correlators, analytically continued to complex frequency, exhibit non-hydrodynamic poles and branch cuts that constrain hydrodynamics. We construct Gaussian Schwin…

A new web of dualities from Majorana Fermions
Andrea Amoretti, Matteo Anselmi, Daniel K. Brattan
We explore new infrared dualities in -dimensional quantum field theories involving Majorana fermions. Building on the recently proposed operator-deformation approach to boso…
