“…It has been shown that the group-theoretic approach to the time evolution of quantum states is equivalent to the corresponding Lewis-Riesenfeld approach and the free-particle dynamics can be reproduced from the dynamics of the time-dependent harmonic oscillator by letting ω ( t ) → 0 for t → ∞ 12 . It is only recently that quantum dynamics of a free particle has been noticed and the time behavior of its semiclassical wave packets has been studied 13 14 15 16 .…”

“…É importante ressaltar que o pacote de onda para partícula é um assunto que podemos encontrar em livros de Mecânica Quântica, como também em artigos, veja, por exemplo, [63]. Nesses casos, contudo, não é discutida a construção do pacote de onda como EC, sendo feito apenas em 2014, no nosso artigo [33].…”
