Entanglement Entropies of the quarter filled Hubbard model
Pasquale Calabrese, Fabian H. L. Essler, Andreas M. Lauchli
We study Renyi and von Neumann entanglement entropies in the ground state of the one dimensional quarter-filled Hubbard model with periodic boundary conditions. We show that they e…

Momentum-Space Entanglement Spectrum of Bosons and Fermions with Interactions
Rex Lundgren, Jonathan Blair, Martin Greiter +3
We study the momentum space entanglement spectra of bosonic and fermionic formulations of the spin-1/2 XXZ chain with analytical methods and exact diagonalization. We investigate t…
