We develop a conformal field theory approach for investigation of the quantum charge, heat, and thermoelectric transport through a quantum impurity fine-tuned to a non-Fermi liquid regime. The non-Fermi-liquid operational mode is associated with the overscreened spin Kondo effect and controlled by the number of orbital channels. The universal low-temperature scaling and critical exponents for Seebeck and Peltier coefficients are investigated for the multichannel geometry. We discuss the universality of Lorenz ratio and power factor beyond the Fermi-liquid paradigm. Different methods of verifying our findings based on the recent experiments are proposed.

过度筛选的近藤状态下的量子热电和热传输：精确的共形场理论结果

我们开发了一种共形场论方法，用于研究通过微调至非费米液体状态的量子杂质的量子电荷，热量和热电传输。非费米液体的工作模式与过筛的自旋近藤效应相关，并受轨道通道数的控制。对于多通道几何结构，研究了塞贝克系数和珀耳帖系数的通用低温标度和临界指数。我们讨论费米液体范式之外的洛伦兹比和功率因数的普遍性。根据最近的实验，提出了不同的方法来验证我们的发现。
