Fisher information, nonclassicality and quantum revivals
E. Romera, F. de los Santos
Wave packet revivals and fractional revivals are studied by means of a measure of nonclassicality based on the Fisher information. In particular, we show that the spreading and the…
Application of new Rényi uncertainty relations to wave packet revivals
Francisco de los Santos, Clara Guglieri, Elvira Romera
Wave packet revivals and fractional revivals are studied by means of newly derived uncertainty relations that involve Rényi entropies and position and momentum dispersions.
Fractional revivals through Rényi uncertainty relations
Elvira Romera, Francisco de los Santos
We show that the Rényi uncertainty relations give a good description of the dynamical behavior of wave packets and constitute a sound approach to revival phenomena by analyzing thr…
Fisher-Shannon product and quantum revivals in wavepacket dynamics
T. García, F. de los Santos, E. Romera
We show the usefulness of the Fisher-Shannon information product in the study of the sequence of collapses and revivals that take place along the time evolution of quantum wavepack…
Zitterbewegung in monolayer silicene in a magnetic field
E. Romera, J. B. Roldán, F. de los Santos
We study the Zitterbewegung in monolayer silicene under a perpendicular magnetic field. Using an effective Hamiltonian, we have investigated the autocorrelation function and the de…
Revival times at quantum phase transitions
Francisco de los Santos, Elvira Romera
The concept of quantum revivals is extended to many-body systems and the implications of traversing a quantum phase transition are explored. By analyzing two different models, the…
