Quantum electrodynamics of equilibrium systems: A rigorous Maxwell-regularized functional-theoretic formulation
A framework for quantum electrodynamics of equilibrium systems is proposed that takes the Maxwell equations as foundational and links them to the structure of density-functional theory for the quantum system. By switching from purely internal observables like the one-particle density to combined internal and external q...
