论文摘要
提出了具有适当初始条件的非线性玻色子扩散方程的精确分析溶液，这些条件涉及超低原子的蒸发冷却，再加上奇异性$ε=μ<0 $的边界条件，并用于计算冷量子气的时间依赖性熵。
Exact analytic solutions of a nonlinear boson diffusion equation with suitable initial conditions that account for evaporative cooling of ultracold atoms, plus boundary conditions at the singularity $ε=μ<0$ are presented, and used to calculate the time-dependent entropy of a cold quantum gas.
