论文摘要
我们制定了一种自发折断的翻译的耗散流体动力学理论,描述了干净的各向同性电子晶体中的电荷密度波。我们确定了新型的线性传输系数,晶格压力,可捕获背景应变和晶体中热膨胀的影响。我们认为,晶格压力是具有自发折断翻译的系统的通用特征,必须在构建和解释全息模型时考虑。我们还提供了全息电子晶体中热和化学膨胀系数的首次计算。
We formulate a theory of dissipative hydrodynamics with spontaneously broken translations, describing charge density waves in a clean isotropic electronic crystal. We identify a novel linear transport coefficient, lattice pressure, capturing the effects of background strain and thermal expansion in a crystal. We argue that lattice pressure is a generic feature of systems with spontaneously broken translations and must be accounted for while building and interpreting holographic models. We also provide the first calculation of the coefficients of thermal and chemical expansion in a holographic electronic crystal.
