论文摘要
我们引入了一种通用且易于访问的实现,用于研究少数特性模型的精确对角线化方法。我们的目的是为该领域的新移民提供一个测试台,以及尝试尝试新颖的优化和近似值的垫脚石。该userguide包括对算法的描述,以及各种复杂顺序的几个示例。特别是,我们使用一种有效的相互作用方法来体现我们的常规,该方法可以修复低能物理学。我们根据现有数据对这种方法进行基准测试,并表明它能够以显着降低的计算成本提供最新的数值结果。
We introduce a generic and accessible implementation of an exact diagonalization method for studying few-fermion models. Our aim is to provide a testbed for the newcomers to the field as well as a stepping stone for trying out novel optimizations and approximations. This userguide consists of a description of the algorithm, and several examples in varying orders of sophistication. In particular, we exemplify our routine using an effective-interaction approach that fixes the low-energy physics. We benchmark this approach against the existing data, and show that it is able to deliver state-of-the-art numerical results at a significantly reduced computational cost.
