摘要

本研究探讨了量子复兴现象,即量子系统的波函数在随时间演变后周期性地返回其初始状态。本研究重点探讨了被限制在带有杂质的量子盒内的电子的弱耦合和强耦合状态,揭示了杂质参数与时间动力学之间错综复杂的关系。这项研究考虑了杂质位置、杂质强度以及铝浓度、温度和静水压力等外部因素对经典周期和复兴时间的影响。通过分析推导和图表分析,这项研究阐明了量子复苏对这些参数的敏感性,为量子力学的基本方面提供了宝贵的见解。虽然没有讨论具体的物理应用,但研究结果为量子热机和其他基于量子的技术提供了启示,强调了理解密闭量子系统中量子复苏的重要性。

Effects of Impurities and Deformations on Electronic Effective Mass in Quantum Revival Time within the Infinite Square Well
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.
