Quantum Interference Phenomena in the Local Polarization Dynamics of Mesoscopic Systems: An NMR Observation
Horacio M. Pastawski, Gonzalo Usaj, Patricia R. Levstein
It was predicted that local spin polarization in a ring of five dipolar coupled spins should present a particular fingerprint of quantum interferences reflecting both the discrete…

Quantum Dynamical Echoes in the Spin 'Diffusion' in Mesoscopic Systems
Horacio M. Pastawski, Patricia R. Levstein, Gonzalo Usaj
The evolution of local spin polarization in finite systems involves interference phenomena that give rise to {\bf quantum dynamical echoes }and non-ergodic behavior. We predict the…
