Entanglement detachment in fermionic systems
Hernán Santos, José Enrique Alvarellos, Javier Rodríguez-Laguna
This article introduces and discusses the concept of entanglement detachment. Under some circumstances, enlarging a few couplings of a Hamiltonian can effectively detach a (possibl…

Engineering large end-to-end correlations in finite fermionic chains
Hernán Santos, José E. Alvarellos, Javier Rodríguez-Laguna
We explore deformations of finite chains of independent fermions which give rise to large correlations between their extremes. After a detailed study of the Su-Schrieffer-Heeger (S…
