Figure 18
Dynamics of the thermal rectification factor \(\Re\) for different values of \(\Delta T\) with and without the Lamb shift. The initial state of qubits is \(|\Phi _3\rangle =\frac{1}{\sqrt{2}}\left[ |0,1\rangle -|1,0\rangle \right]\) and all other parameters are set as in Fig. 14. In the presence of the Lamb shift, the cutoff frequency of the Ohmic spectral density is \(\omega _D=1000 J\). The panels (a) and (b) correspond to the symmetric coupling setting \((\varepsilon =0)\) and the asymmetric coupling setting \((\varepsilon =1)\), respectively.
