We propose a simple model of coupled heat and particle transport based on zero-dimensional classical deterministic dynamics, which is reminiscent of a railway switch whose action is a function only of the particle's energy. It is shown that already in the minimal three-terminal model, where the second terminal is considered as a probe with zero net particle and heat currents, one can find extremely asymmetric Onsager matrices as a consequence of time-reversal symmetry breaking of the model. This minimalistic transport model provides a better understanding of thermoelectric heat engines in the presence of time-reversal symmetry breaking.
我们提出了一个基于零维经典确定性动力学的热与粒子耦合输运的简单模型，它让人联想到一种铁路道岔，其动作仅取决于粒子的能量。结果表明，即使在最小的三端模型中，其中第二个端被视为净粒子流和热流为零的探针，由于模型的时间反演对称性破缺，也能发现极其不对称的昂萨格矩阵。这种简约的输运模型有助于更好地理解存在时间反演对称性破缺时的热电热机。
