我们用量子蒙特卡罗和无核全组态技术计算了外势中中子滴的性质。外部井的性质是不同的，以检查不同的密度分布。我们比较了一些核哈密顿理论给出的中子滴定结果，包括现实中的两体相互作用以及几种三体作用力。我们计算了中子滴的一系列性质：基态能量、自旋轨道分裂、激发能、径向密度和均方根半径。我们比较了其中几个哈密顿量的中子物质的状态方程。我们的结果可以作为测试其他多体技术和约束能量密度泛函性质的基准。
We calculate properties of neutron drops in external potentials using both quantum Monte Carlo and no-core full configuration techniques. The properties of the external wells are varied to examine different density profiles. We compare neutron drop results given by a selection of nuclear Hamiltonians, including realistic two-body interactions as well as several three-body forces. We compute a range of properties for the neutron drops: ground-state energies, spin-orbit splittings, excitation energies, radial densities and rms radii. We compare the equations of state for neutron matter for several of these Hamiltonians. Our results can be used as benchmarks to test other many-body techniques and to constrain properties of energy-density functionals.
