“…Recently, it was shown that the influence of spiral dislocation gives rise to a non-null revival time in the harmonic oscillator [13]. Additionally, the classical periods and revival times of electron currents in several bulk nanostructured semiconductor materials were computed in [14]. The hallmark concept of periodic collapse and revival of coherence in a room-temperature ensemble of quantum dots is demonstrated in [15].…”

Quantum revival phenomena, wherein the wave function of a quantum system periodically returns to its initial state after evolving in time, are investigated in this study. Focusing on electrons confined within a quantum box with an impurity, both weak- and strong-coupling regimes are explored, revealing intricate relationships between impurity parameters and temporal dynamics. This investigation considers the influence of impurity position, impurity strength, and external factors such as aluminum concentration, temperature and hydrostatic pressure on classical periods and revival times. Through analytical derivations and graphical analyses, this study elucidates the sensitivity of quantum revivals to these parameters, providing valuable insights into the fundamental aspects of quantum mechanics. While no specific physical applications are discussed, the findings offer implications for quantum heat engines and other quantum-based technologies, emphasizing the importance of understanding quantum revivals in confined quantum systems.

Additionally, the classical periods and revival times of electron currents in several bulk nanostructured semiconductor materials were computed in [14]. Quantum revivals within relativistic theory can be explored in [15], and further investigations concerning exact quantum revivals for the Dirac equation are detailed in [16].…”
