Figure 17
Dynamics of the thermal rectification factor \(\Re\) for different values of \(\Delta T\) with and without the Lamb shift. The initial state of the qubits is \(|\Phi _1\rangle =|0,0\rangle\) and other parameters are set as same as Fig. 12. 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.
