论文摘要
我们基于先前衍生的准确溶解的非线性玻色子扩散方程（NBDE），计算钾蒸气中玻色的时间依赖性形成。从初始温度$ t_ \ mathrm {i} $到最终温度$ t_ \ mathrm {f} $以下的临界值和BEC形成的热量突然的能量淬灭后的突然能量淬火到最终温度$ t_ \ mathrm {f} $使用NBDE的封闭形式分析解决方案。将时间相关的冷凝水分与可用的$^{39} $ K数据进行比较，以用于各种散射长度。
We calculate the time-dependent formation of Bose--Einstein condensates (BECs) in potassium vapours based on a previously derived exactly solvable nonlinear boson diffusion equation (NBDE). Thermalization following a sudden energy quench from an initial temperature $T_\mathrm{i}$ to a final temperature $T_\mathrm{f}$ below the critical value and BEC formation are accounted for using closed-form analytical solutions of the NBDE. The time-dependent condensate fraction is compared with available $^{39}$K data for various scattering lengths.
