Thermal and thermoelectric response from Keldysh formalism with application to gapped Dirac fermions |
The intrinsic contribution (dashed blue curve), side-jump contribution (dash-dotted green curve), and their sum (solid red curve) to thermal Hall conductivity (a), and thermoelectric Hall conductivity (b) as a function of the Fermi energy ε F. The thermal Hall conductivity is measured in units of and the thermoelectric Hall conductivity is measured in units of . |
