Seebeck effect on a weak link between Fermi and non-Fermi liquids
T. K. T. Nguyen and M. N. Kiselev
We propose a model describing Seebeck effect on a weak link between two quantum systems with fine-tunable
ground states of Fermi and non-Fermi liquid origin. The experimental realization of the model can be achieved
by utilizing the quantum devices operating in the integer quantum Hall regime [Z. Iftikhar et al., Nature (London)
526, 233 (2015)] designed for detection of macroscopic quantum charged states in multichannel Kondo systems.
We present a theory of thermoelectric transport through hybrid quantum devices constructed from quantumdot–
quantum-point-contact building blocks. We discuss pronounced effects in the temperature and gate voltage
dependence of thermoelectric power associated with a competition between Fermi and non-Fermi liquid behaviors.
High controllability of the device allows to fine tune the system to different regimes described by multichannel
and multi-impurity Kondo models.
