Abstract
The evolution of wavepackets resulted in new class large scale interference effects: the formation of highly regular spatiotemporal patterns in the QM probability with the key mechanism for this pair interference between eigen-modes of the system and the degeneracy of this interference is presented. The new patterns are discovered in the probability density of a particle in an infinitely deep square well, by numerical simulations of the evolution of a Gaussian wavepacket. Recently, a quantum carpet under more general conditions offered its universal explanation and predicted distinct curved patterns in general case of an anharmonic potentials is observed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
