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…

The two-particle density matrix of a Luttinger liquid
Harini Radhakrishnan, Matthias Thamm, Hatem Barghathi +2
The paper derives an exact finite-size formula for the equal-time two‑particle reduced density matrix of spinless fermions in a Tomonaga‑Luttinger liquid, revealing how its decay a…
