摘要：

A study was conducted to determine what may happen with the decoherence process when there is a time-dependent setting. Following this, a simple toy model that naturally includes time-dependent features was addressed. Based on time-dependent Hamiltonian or by changing the temperature of the bath, it was shown that even after classicalization was reached, the system may again display quantum behavior.
