摘要翻译：
我们发现，轻、重费米子原子弱束缚分子系统具有长程的分子间排斥作用，当质量比超过某一临界值时，系统会发生气晶量子跃迁。当临界质量比大于100时，对于填充因子较小的重原子，这种晶序可以观察到为光晶格中的超晶格。我们还发现这个新体系在分子弛豫到深束缚态和三聚体形成过程中是足够稳定的。

英文摘要：
We show that the system of weakly bound molecules of heavy and light fermionic atoms is characterized by a long-range intermolecular repulsion and can undergo a gas-crystal quantum transition if the mass ratio exceeds a critical value. For the critical mass ratio above 100 obtained in our calculations, this crystalline order can be observed as a superlattice in an optical lattice for heavy atoms with a small filling factor. We also find that this novel system is sufficiently stable with respect to molecular relaxation into deep bound states and to the process of trimer formation.
