Description

We derive differential equations from path-integral-based non-equilibrium quantum field theory that cover the dynamics and spectrum of non-relativistic two-body fields for any environment. For concreteness of the two-body fields, we choose the full potential non-relativistic quantum electrodynamics Lagrangian in this work. After closing the correlation function hierarchy of these equations and performing consistency checks with previous literature under certain limits, we demonstrate the range of physics applications. This includes cosmology such as dark matter in the primordial plasma, quarkonia inside a quark-gluon plasma, and other phenomena in condensed or strongly correlated matter physics.
