L-mode coefficients exceed R-mode coefficients, especially for Nernst.

Seebeck coefficient is significantly enhanced in 2-D temperature profiles.

Chiral quasifermion masses restrict magnetic field and temperature ranges.

Abstract

The lifting of the degeneracy between L- and R-modes of massless flavors in a weakly magnetized thermal QCD medium leads to a novel phenomenon of chirality dependence of the thermoelectric tensor, whose diagonal and non-diagonal elements are the Seebeck and Hall-type Nernst coefficient, respectively. Both coefficients in L-mode have been found to be greater than their counterparts in R-mode, however the disparity is more pronounced in the Nernst coefficient. Another noteworthy observation is the impact of the dimensionality of temperature (T) profile on the Seebeck coefficient, wherein we find that the coefficient magnitude is significantly enhanced (one order of magnitude) in the 2-D setup, compared to a 1-D T profile. Further, the chiral dependent quasifermion masses constrain the range of magnetic field (B) and T in a manner so as to enforce the weak magnetic field (eB << T^2 ) condition.
