摘要翻译：
我们从理论上研究了从囚禁的费米子原子的正常气体出发，绝热地增加一个光晶格，达到Hubbard模型的反铁磁相的可能性。考虑平均场解附近的涨落，通过计算Neel态熵，确定了三维正方形晶格对初始温度和原子数的要求。我们发现这些涨落对绝热达到Neel态有重要的限制。

英文摘要：
We theoretically study the possibility of reaching the antiferromagnetic phase of the Hubbard model by starting from a normal gas of trapped fermionic atoms and adiabatically ramping up an optical lattice. Requirements on the initial temperature and the number of atoms are determined for a three dimensional square lattice by evaluating the Neel state entropy, taking into account fluctuations around the mean-field solution. We find that these fluctuations place important limitations on adiabatically reaching the Neel state.
