n this study, thermoelectric conductance of a Dirac material was investigated .We have considered Weyl semimetals and
topological insulators in this study. We considered an edge mode for a 2D and 3D topological insulator. For the perfect one
dimensional conductor our fermionic formulation agrees with the bosonization result. Back scattering was allowed in the
presence of a magnetic field and thermal conductivity was determined. The conserved current and the thermal conductivity
were computed within a fermionic formulation. We found that at finite temperature, due to backscattering alone, the electric
conductance, thermoelectric conductance and thermal conductance decreases with the increase in magnetic field. At finite
temperatures, weak localization effects are small and can be ignored. We confirmed the experimental results in a magnetic field
for 3D topological insulator. An experimental set-up was proposed to test our theory.
