AI 中文摘要
温差维持的热流会产生物质梯度,例如硬核气体的原子模拟中已观测到该现象。我们采用路径系综理论,通过图上动力学描述耦合的热与扩散输运;该模型由单次平衡模拟校准,可准确预测硬核气体在宽温度梯度下的非平衡质量分布,还能通过解析表达式估算索雷特系数等输运性质。
英文摘要
Heat flow sustained by a temperature difference generates a gradient of matter as observed, for example, in atomistic simulations of hard-core gases. We use path-ensemble theory to represent the coupled thermal and diffusive transport by dynamics on a graph. Calibrated from a single equilibrium simulation, this model accurately predicts nonequilibrium mass distribution in a hard-core gas across a wide range of applied temperature gradients. It also enables estimation of transport properties, such as the Soret coefficient, using analytical expressions.
