Fig. 6: Calculated Nernst coefficient under variation of further parameters.
a Nernst coefficient as a function of the chemical potential μ for two different values of g and fixed temperature kBT = 0.01. The broad maximum at intermediate μ values (for g ≠ 0) is comparable with the observed behaviour of the Nernst effect as a function of doping as it has been found by our measurements. For comparison, we also show the result without taking into account nematic coupling (g = 0), which shows a very reduced amplitude. b Nernst coefficient as a function of temperature for different values of μ and fixed g = 0.1. As observed in the experiments, we find a μ-dependent low temperature maximum followed by a rapid decrease and saturation at high T. The maximum appears when the thermal energy kBT is of the same order as the experimentally found value kBTc for the superconducting Tc.
