Abstract

Decades ago, Gurzhi proposed that if momentum-conserving collisions prevail among heat-carrying phonons in insulators and charge-carrying electrons in metals, hydrodynamic features will become detectable. In this paper, we will review the experimental evidence emerging in the last few years supporting this viewpoint and raising new questions. The focus of the paper will be bulk crystals without (or with a very dilute concentration of) mobile electrons and steady-state thermal transport. We also discuss the possible link between this field of investigation and other phenomena, such as the hybridization of phonon modes and the phonon thermal Hall effect.

块状绝缘体和半金属中的声子流体力学

几十年前，古尔日提出，如果绝缘体中携带热量的声子和金属中携带电荷的电子之间发生动量守恒碰撞，流体力学特征就会被探测到。在本文中，我们将回顾过去几年中出现的支持这一观点并提出新问题的实验证据。本文的重点是没有（或只有非常稀少的）移动电子的块状晶体和稳态热传输。我们还将讨论这一研究领域与其他现象（如声子模式杂化和声子热霍尔效应）之间可能存在的联系。

期刊介绍： Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies. Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
