Entanglement of Inhomogeneous Free Bosons and Orthogonal Polynomials
Pierre-Antoine Bernard, Rafael I. Nepomechie, Gilles Parez +3
In this paper, we investigate the ground-state entanglement entropy in inhomogeneous free-boson models in one spatial dimension. We develop a powerful method to extract the leading…
Entanglement Hamiltonian and orthogonal polynomials
Pierre-Antoine Bernard, Riccarda Bonsignori, Viktor Eisler +2
We study the entanglement Hamiltonian for free-fermion chains with a particular form of inhomogeneity. The hopping amplitudes and chemical potentials are chosen such that the singl…
Fermionic logarithmic negativity in the Krawtchouk chain
Gabrielle Blanchet, Gilles Parez, Luc Vinet
The entanglement of non-complementary regions is investigated in an inhomogeneous free-fermion chain through the lens of the fermionic logarithmic negativity. Focus is on the Krawt…
Absence of logarithmic enhancement in the entanglement scaling of free fermions on folded cubes
Pierre-Antoine Bernard, Zachary Mann, Gilles Parez +1
This study investigates the scaling behavior of the ground-state entanglement entropy in a model of free fermions on folded cubes. An analytical expression is derived in the large-…
Entanglement of inhomogeneous free fermions on hyperplane lattices
Pierre-Antoine Bernard, Nicolas Crampé, Rafael I. Nepomechie +3
We introduce an inhomogeneous model of free fermions on a -dimensional lattice with continuous parameters that control the hopping strength between adjacent sites…
