论文摘要
最近已经显示，在一维硬点气体中，有一种机制可以在热浴之间诱导负差分热电阻（NDTR）。我们在更一般的更高维流体中检查了这种机制，该机制由多粒子碰撞动力学描述。我们考虑在有限的三维空间的有限立方区域，每个端都与热浴接触。基于分析结果和数值模型，我们发现NDTR的机制也适用于具有弱相互作用的高维流体系统，并且对混合流体非常健壮。我们的结果大大提高了热浴和启动新方向引起的NDTR知识，以探索微型和纳米系统中的流体热晶体管。
It has recently been shown that in one-dimensional hard-point gases, there is a mechanism that induces negative differential thermal resistance (NDTR) between heat baths. We examine this mechanism in more general higher dimensional fluids described by multiparticle collision dynamics. We consider fluids in a finite cuboid region of three-dimensional space with each end in contact with a heat bath. Based on analytical results and numerical models, we find that the mechanism underlying NDTR also works for high-dimensional fluidic systems with weak interactions and is very robust to mixed fluids. Our results significantly advance knowledge of NDTR induced by heat bath and illuminate new directions to explore in fabricating fluid thermal transistors in micro- and nanosystems.
