摘要: 给出了Jaynes-Cummings 模型在大光子数近似下原子状态与自旋分量不确定度的数学表达式,发现原子状态与自旋的不确定程度在自旋各分量之间相互转换,但却能保持总不确定程度的守恒.

关键词: Jaynes-Cummings 模型, 不确定度关系, 自旋

Abstract: We derive the expression for the uncertainty between atom state and spin component in large photons. It has found that the uncertainty can transfer between the spin component but hold conservation of whole uncertainty.

Key words: Jaynes-Cummings model, uncertainty principle, spin
