Trie-based ranking of quantum many-body states

M Wallerberger, K Held - Physical Review Research, 2022 - APS
Ranking bit patterns—finding the index of a given pattern in an ordered sequence—is a
major bottleneck in scaling up numerical quantum many-body calculations, as fermionic and …

A new pathway to impact ionization in a photo-excited one-dimensional ionic Hubbard model

Z Cheng, L Yang, X Hu, H Lu, Z Huang, L Du - arXiv preprint arXiv …, 2024 - arxiv.org
