Tiêu đề: Thermoelectric transport in a three channel charge Kondo circuit

Tóm tắt: In this talk I will present our theoretical work about the thermoelectric transport through a circuit implementation of the three-channel charge Kondo model quantum simulator [Z. Iftikhar et al., Science 360, 1315 (2018)]. The universal temperature scaling law of the Seebeck coefficient is computed perturbatively approaching the non-Fermi liquid strong coupling fixed point using abelian bosonization technique. The predicted T^{1/3} log T scaling behaviour of the thermoelectric power sheds a light on the properties of Z_{3} emerging parafermions and gives an access to exploring pre-fractionalized zero modes in the quantum transport experiments. We discuss a generalization of approach for investigating a multi-channel Kondo problem with emergent Z_{N} to Z_{M} crossovers between “weak” non-Fermi liquid regimes corresponding to different low-temperature fixed points
