• Abstract: We investigate decoherence mechanisms in open quantum systems using quantum field theory techniques and the quantum Boltzmann equation. Specifically, we focus on decoherence through Bremsstrahlung emission, a fundamental process in quantum electrodynamics leading to coherence loss. By applying quantum field theory techniques and quantum Boltzmann equation, we model the fermion-photon interaction in the Stern-Gerlach interferometer and analyze the induced dephasing factor. Our approach offers significant advancements in understanding decoherence and its potential applications in quantum sensing and atomic interferometry. We demonstrate the accuracy of our method by comparing results to classical Bremsstrahlung.
