We present a theoretical study of the quantum corrections to the revival time due to finite tunneling in the collapse and revival of matter-wave interference after a quantum quench. We study hard-core bosons in a superlattice potential and the Bose-Hubbard model by means of exact numerical approaches and mean-field theory. We consider systems without and with a trapping potential present. We sh...

Vinyl revival refers to the growth of vinyl record sales in twenty-first century. Initially thought be a short-term trend when first reported 2008 and 2009, popularity LPs among music consumers has since become perennial talking point for industry observers, particularly as CD have steadily declined (figs. 1 2). Observers typically contextualized popular revivals within ideas nostalgia, roots, ...

We present a generic treatment of wave-packet revivals for quantum-mechanical systems. This treatment permits a classification of certain ideal revival types. For example, wave packets for a particle in a one-dimensional box are shown to exhibit perfect revivals. We also examine the revival structure of wave packets for quantum systems with energies that depend on two quantum numbers. Wave pack...

This paper begins with an examination of the revival structure and long-term evolution of Rydberg wave packets for hydrogen. We show that after the initial cycle of collapse and fractional/full revivals, which occurs on the time scale t rev , a new sequence of revivals begins. We find that the structure of the new revivals is different from that of the fractional revivals. The new revivals are ...

Revivals of the coherent states of a deformed, adiabatically and cyclically varying oscillator Hamiltonian are examined. The revival time distribution is exactly that of Poincaré recurrences for a rotation map: only three distinct revival times can occur, with specified weights. A link is thus established between quantum revivals and recurrences in a coarse-grained discrete-time dynamical system.

BACKGROUND In less than a decade, Morocco reportedly saw cannabis cultivation decrease by 65%, and hashish production is widely believed to have followed the same trend. Yet large anomalies exist between the alleged fall of hashish production in Morocco and international seizure data. While no explanation for such a discrepancy existed, the main hypothesis was that cannabis cultivation and hash...
