Sudden vanishing and reappearance of nonclassical effects: General occurrence of finite-time decays and periodic vanishings of nonclassicality and entanglement witnesses

Por • 8 feb, 2011 • Category: Leyes

Recently, analyses of phenomena exhibiting finite-time decay of quantum entanglement have attracted much attention. Such decay is often referred to as sudden vanishing (sudden death) of entanglement, which can be followed by its sudden reappearance (sudden rebirth).

Evidence of strategic periodicities in collective conflict dynamics

We demonstrate the existence of periodicities that are not directly coupled to environmental cycles or known ultraridian mechanisms.
