Dynamical Symmetry and the Thermofield State at Large <i>N</i>
We discuss thermofield double QFT at real time, in the large <i>N</i> limit. First, we establish a (dynamical) symmetry, which we argue holds in general for the real-time portion of the Schwinger–Kelydish contour. At large <i>N</i>, this symmetry is seen to generate a one-par...
