Thermopower of the device as a function of temperature in units of $(k_{B} / e)$ at the topological transition of the RM chains. $S > 0$ correspond to $μ = ϵ = + 0.1$ , and $μ = ϵ = + 3.3 \times 10^{- 4}$ (light curve). Negative thermopower ( $S < 0$ ) corresponds to $μ = ϵ = - 0.1$ and $μ = ϵ = - 3.3 \times 10^{- 4}$ (light curve). The light color curves show the trend to the results the SSH chain with $ϵ = 0$ . The energy scale for the low temperature saturation of the thermopower is given by the difference in site energies, $2 ϵ$ . The numerical results for the saturation values, $S (T = 0) \approx \pm 1.38634$ are in close agreement with $S_{0} = \pm 2 ln 2 \approx \pm 1.38634$ , as discussed in the text.
