量子梯度质量系统中的热整流

Thermal rectification in quantum graded mass systems

Emmanuel Pereira

摘要:

我们证明了具有自洽库的谐振子梯度质量量子链中热整流的存在。我们的分析研究使我们能够确定导致这种效果的成分。在这个有效的、简单的模型(代表梯度质量材料,可以在实践中构建的系统)中存在整流,表明梯度质量量子系统中的整流可能是一种普遍存在的现象。此外,由于该模型的经典版本不存在整流,我们的结果表明,在这里,整流是量子统计的直接结果。

英文摘要:

We show the existence of thermal rectification in the graded mass quantum chain of harmonic oscillators with self-consistent reservoirs. Our analytical study allows us to identify the ingredients leading to the effect. The presence of rectification in this effective, simple model (representing graded mass materials, systems that may be constructed in practice) indicates that rectification in graded mass quantum systems may be an ubiquitous phenomenon. Moreover, as the classical version of this model does not present rectification, our results show that, here, rectification is a direct result of the quantum statistics.
