Single-Site Entanglement of Fermions at a Quantum Phase Transition
Daniel Larsson, Henrik Johannesson
abstract: We show that the single-site entanglement of a generic spin-1/2 fermionic
lattice system can be used as a reliable marker of a finite-order quantum phase
transition, given certain provisos. We discuss the information contained in the
single-site entanglement measure, and provide illustrations from the
Mott-Hubbard metal-insulator transitions of the one-dimensional Hubbard model,
and the Hubbard model with long-range hopping.
