Abstract
We present a removal of the infrared divergences in the Beliaev-Dyson equation for spin-1 spinor Bose–Einstein-condensed systems. Unlike the Beliaev-Dyson equations for spin-0 Bose–Einstein-condensates, the Beliaev-Dyson equations for spin-1 spinor Bose–Einstein-condensates are given as \(6\times 6\) matrix elements. The divergent terms remaining in a ferromagnetic phase and a polar phase are contained identically in some elements of self-energy matrix. Based on experiences removing infrared divergences in spin-0 Bose–Einstein-condensates and identity of divergent terms, we remove the infrared divergences in Beliaev-Dyson equation for spinor Bose–Einstein-condensed systems.
期刊介绍：
International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
