General formula for the thermoelectric transport phenomena based on Fermi liquid theory: Thermoelectric power, Nernst coefficient, and thermal conductivity [PDF]

Physical Review B, 2003
On the basis of the linear response transport theory, the general expressions for the thermoelectric transport coefficients, such as thermoelectric power (S), Nernst coefficient ( ), and thermal conductivity ( ), are derived by using the Fermi liquid theory.

Electrical and thermal transport in van der Waals magnets 2H-M_{x}TaS_{2} (M=Mn, Co)

Physical Review Research, 2022
We report a detailed study of electrical and thermal transport properties in 2H-M_{x}TaS_{2} (M=Mn, Co) magnets where M atoms are intercalated in the van der Waals gap. The intercalation induces ferromagnetism (FM) with an easy-plane anisotropy in 2H-Mn_{

Spin thermopower in the overscreened Kondo model

New Journal of Physics, 2013
Using the numerical renormalization group method, we study the spin thermopower in the two-channel spin-1/2 Kondo model. The non-Fermi liquid properties related to the overscreening of the impurity spin crucially affect the response of the system to the ...
