Quantum correlations, entanglement spectrum, and coherence of the two-particle reduced density matrix in the extended Hubbard model
We study the ground state properties of the one-dimensional extended Hubbard model at half filling from the perspective of its particle reduced density matrix. We focus on the reduced density matrix of two fermions and perform an analysis of its quantum correlations and coherence along the different...
