我们提供了一个双组分费米系统在谐振子势阱中与吸引相互作用的量子蒙特卡罗计算。我们研究了相互作用的散射长度和有效范围的作用，并展示了其在改变这些系统结构中的壳层效应方面的重要作用。我们表明，在强相互作用区域，即散射长度较大时，壳层效应的主导作用归因于有效范围。这些结论对核物理，特别是对富中子系统非常重要，并为开展有助于解释原子核中壳层效应消失的新原子实验开辟了道路。
英文摘要
We provide quantum Monte Carlo calculations of a two-component Fermi system interacting with an attractive interaction confined in harmonic traps. We investigate the role of the interaction's scattering length and effective range and show its important role in modifying shell effects in the structure of these systems. We show that in the strongly interacting regime, where the scattering length is large, the dominant role to shell effects is due to the effective range. These conclusions are very relevant for nuclear physics, in particular for neutron-rich systems, and open the way to perform new atomic experiments that can help to explain the disappearance of shell-effects in nuclei.
