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

Infinite temperature spin dynamics in the asymmetric Hatsugai-Kohmoto model
Ãdám Bácsi, Doru Sticlet, Catalin Pascu Moca +1
We focus on the infinite temperature dynamical spin structure factor of the asymmetric Hatsugai-Kohmoto model, the relative of the asymmetric Hubbard model. It is characterized by…

Non-equilibrium dynamics of superconductivity in the Hatsugai-Kohmoto model
Ãdám Bácsi, Balázs Dóra
We study the non-equilibrium dynamics of the superconducting order parameter in the Hatsugai-Kohmoto (HK) model. In the absence of superconductivity, its ground state is a non-Ferm…
