论文摘要
能源运输可以揭示有关其他运输探针以外的多体系统相互作用的信息。特别是，在一个维度上，已经表明能量电流与中心电荷成正比，从而揭示了有关关键系统自由度的信息。在这项工作中，我们在两种情况下明确验证了基于显式微观计算的翻译系统的两种情况。更重要的是，我们将结果推广到非翻译不变设置，并使用它来研究两个具有不同中心电荷的子系统的复合系统。我们发现瓶颈效应意味着较小的中央电荷限制了能量传输。
Energy transport can reveal information about interacting many-body systems beyond other transport probes. In particular, in one dimension it has been shown that the energy current is directly proportional to the central charge, thus revealing information about the degrees of freedom of critical systems. In this work, we explicitly verify this result in two cases for translationally invariant systems based on explicit microscopic calculations. More importantly, we generalise the result to non-translation invariant setups and use this to study a composite system of two subsystems possessing different central charges. We find a bottleneck effect meaning the smaller central charge limits the energy transport.
