Role of Nambu–Goldstone Mode in Trapped Bose–Einstein Condensation
Y. Yamanaka, Masahiko Okumura, M. Mine
The system of the trapped Bose–Einstein condensation is investigated from the viewpoint of Quantum Field Theory. It is pointed out that the Nambu–Goldstone mode, which is a discrete mode due to the trapping potential, creates observable effects through fluctuations. The way how the Nambu–Goldstone mode is treated is not unique. The introduction of quantum coordinates is a possible candidate.
