Emergent modular Luttinger liquid from spin-partitioned entanglement in the one-dimensional Hubbard model

Ádám Bácsi, Catalin Pascu Moca, Balázs Dóra

We study the spin-partitioned entanglement Hamiltonian of the one-dimensional repulsive Hubbard model. By combining bosonization with exact diagonalization, we show that tracing ou…
