混沌、热力学和量子力学:天体动力学的应用

Chaos, Thermodynamics and Quantum Mechanics: an Application to Celestial Dynamics

David Vitali, Paolo Grigolini

摘要:

我们使用Zurek最近所做的[e-print quant-ph/9802054],整个太阳系作为案例研究来解决混沌系统中量子经典对应的问题:作者表明,行星运动的经典性是由环境引起的退相干所确保的。我们表明,等效的结果提供的自发波动的理论,这些后者的理论,在某些情况下,在一个更快的过程中的退相干的结果。我们表明,作为一个额外的好处,自发涨落的假设使得有可能真正从力学中推导出热力学,即,没有隐含地假设热力学。

英文摘要:

We address the issue of the quantum-classical correspondence in chaotic systems using, as recently done by Zurek [e-print quant-ph/9802054], the solar system as a whole as a case study: this author shows that the classicality of the planetary motion is ensured by the environment-induced decoherence. We show that equivalent results are provided by the theories of spontaneous fluctuations and that these latter theories, in some cases, result in a still faster process of decoherence. We show that, as an additional benefit, the assumption of spontaneous fluctuation makes it possible to genuinely derive thermodynamics from mechanics, namely, without implicitly assuming thermodynamics.
