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…

Free-Fermion entanglement and orthogonal polynomials
Nicolas Crampé, Rafael I. Nepomechie, Luc Vinet
We present a simple construction for a tridiagonal matrix that commutes with the hopping matrix for the entanglement Hamiltonian of open finite free-Fermion chains a…
