Hubbard-assisted stability of Hatsugai-Kohmoto correlations in a one-dimensional open chain

Yan-Xiao Wang, Yin Zhong

The paper studies how adding an onsite Hubbard repulsion affects the Hatsugai‑Kohmoto model in a half‑filled one‑dimensional spinful fermion chain, finding that the Hubbard term ca…
