Dynamical invariants and nonadiabatic geometric phases in open quantum systems
M. S. Sarandy, E. I. Duzzioni, M. H. Y. Moussa
We introduce an operational framework to analyze non-adiabatic Abelian and non-Abelian, cyclic and non-cyclic, geometric phases in open quantum systems. In order to remove the adia…

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…
