论文摘要
由于重量的离散性，由于重量的离散性，像重量这样的均匀力已被证明禁止玻色网凝结（BEC）。我们表明，即使在称为近似连续极限（ACL）的情况下，即使通风频谱被视为连续的，BEC也是禁止的。 BEC的缺失是由于量子和经典地面之间的有限差$ε_0$。进行了一项彻底的研究，显示了Bose-Einstein冷凝物在低于虚构BEC温度$ t_f $的温度下增长的方式，这是由极限$ε_0\ rightArrow0 $造成的。与某些实验数据的比较表明，刚性壁储层中的限制与谐波陷阱之间的差异。
A uniform force like the weight has been shown to forbid Bose-Einstein condensation (BEC), due to the discreteness of the Airy spectrum, resulting from the weight. We show that BEC is forbidden even if the Airy spectrum is treated as continuous, in what we call the approximate continuous limit (ACL). The absence of BEC is due to the finite difference $ε_0$ between the quantum and the classical ground level. A thorough study is made, showing the way the Bose-Einstein condensate grows, at temperatures lower than the fictious BEC temperature $T_f$, resulting from the limit $ε_0\rightarrow0$. A comparison with some experimental data shows the difference between the confinement in a rigid-wall reservoir and in a harmonic trap.
