Entanglement Entropy in Random Quantum Spin-S Chains
A. Saguia, M. S. Sarandy, B. Boechat +1
We discuss the scaling of entanglement entropy in the random singlet phase (RSP) of disordered quantum magnetic chains of general spin-S. Through an analysis of the general structu…

Entanglement and Quantum Phases in the Anisotropic Ferromagnetic Heisenberg Chain in the Presence of Domain Walls
F. C. Alcaraz, A. Saguia, M. S. Sarandy
We discuss entanglement in the spin-1/2 anisotropic ferromagnetic Heisenberg chain in the presence of a boundary magnetic field generating domain walls. By increasing the magnetic…
