閉じ込めポテンシャル中のBose-Einstein凝縮の場の理論による記述と数値計算による解析(熱場の量子論とその応用,研究会報告)

抄録

The Bose-Einstein condensation in recent experiments is formulated as a problem in thermal quantum field theory. From this formulation, we carry out numerical analysis so as to investigate effects of quantum and thermal fluctuation to the condensate phase and properties of quasi-particles in this situation.
