粗化系统中的热交换

Heat exchanges in coarsening systems

Federico Corberi, Giuseppe Gonnella, Antonio Piscitelli

摘要:

本文是一个贡献的理解老化系统的热性能,在统计上独立的自由度,在很大程度上分离的时间尺度预计共存。专注于淬火铁磁体的原型情况下,快速和缓慢的模式可以分别关联到大部分的粗化域和它们的接口的波动,我们进行了一组专门设计来计算不同的自由度之间的热交换的数值实验。我们的研究促进了一个方案,快速模式作为一个平衡水库,接口可以释放热量,通过一种机制,允许快速和缓慢的程度,以保持其统计特性独立。

英文摘要:

This paper is a contribution to the understanding of the thermal properties of aging systems where statistically independent degrees of freedom with largely separated timescales are expected to coexist. Focusing on the prototypical case of quenched ferromagnets, where fast and slow modes can be respectively associated to fluctuations in the bulk of the coarsening domains and to their interfaces, we perform a set of numerical experiments specifically designed to compute the heat exchanges between different degrees of freedom. Our studies promote a scenario with fast modes acting as an equilibrium reservoir to which interfaces may release heat through a mechanism that allows fast and slow degrees to maintain their statistical properties independent.
