摘要

在这项工作中,我们研究了旋转对由径向势描述的量子点物理性质的影响。通过求解系统的Schrödinger方程,分析了旋转和约束之间的相互作用,得到了作为角速度函数的能级和波函数。我们计算了关键的热磁性质,包括态密度、磁化强度、熵和热容。我们的研究结果表明,旋转引起了能谱的显著改变,消除了简并并产生了类似于de Haas-van Alphen和aharonov - bohm型振荡的磁化振荡行为。此外,我们观察到类似于磁热效应的效应,在绝热过程中,角速度的增加导致温度的降低。这些结果揭示了旋转效应影响量子系统的潜力,并为介观物理学的未来研究提供了见解。

Effects of rotation on the thermo-magnetic properties of a quantum dot
In this work, we investigate the effects of rotation on the physical properties of a quantum dot described by a radial potential. The interplay between rotation and confinement is analyzed by solving the Schrödinger equation for the system, yielding energy levels and wavefunctions as functions of angular velocity. We compute key thermo-magnetic properties, including the density of states, magnetization, entropy, and heat capacity. Our results demonstrate that rotation induces significant modifications to the energy spectrum, removing degeneracies and generating oscillatory behaviors in magnetization akin to de Haas-van Alphen and Aharonov–Bohm-type oscillations. Furthermore, we observe an effect analogous to the magnetocaloric effect, where an increase in angular velocity leads to a decrease in temperature during adiabatic processes. These results reveal the potential of rotational effects to influence quantum systems and provide insights for future studies in mesoscopic physics.
