PVT系统的动态相变
Dynamic Phase Transitions in PVT Systems
摘要：
本文的主要目的有两个。首先，我们介绍了相变动力学的一些一般原则，包括一个新的动态过渡分类方案，和Ginzburg-Landau理论建模平衡相变。第二，应用一般原理和新近发展的动态相变理论研究PVT系统的动态相变。特别地，我们建立了一个新的含时Ginzburg-Landau模型，并对其进行了动态跃迁分析。值得指出的是，新的动态相变理论，以及动态分类方案和新的含时平衡相变的金兹伯格-朗道模型可以用于其他相变问题，包括例如铁磁性和超流性，这将在其他地方报道。此外，本文对PVT系统的分析导致了一些物理预测，这些预测从物理角度来看是不清楚的。
英文摘要：
The main objective of this article are two-fold. First, we introduce some general principles on phase transition dynamics, including a new dynamic transition classification scheme, and a Ginzburg-Landau theory for modeling equilibrium phase transitions. Second, apply the general principles and the recently developed dynamic transition theory to study dynamic phase transitions of PVT systems. In particular, we establish a new time-dependent Ginzburg-Landau model, whose dynamic transition analysis is carried out. It is worth pointing out that the new dynamic transition theory, along with the dynamic classification scheme and new time-dependent Ginzburg Landau models for equilibrium phase transitions can be used in other phase transition problems, including e.g. the ferromagnetism and superfluidity, which will be reported elsewhere. In addition, the analysis for the PVT system in this article leads to a few physical predications, which are otherwise unclear from the physical point of view.
