Efficient enhancement of the thermoelectric effect due to the Majorana zero modes coupled to one quantum-dot system

By considering Majorana zero modes to laterally couple to the quantum dot, we evaluate the thermoelectric effect in one single-dot system. The calculation results show that if one Majorana zero mode couples to the dot, the thermoelectric effect will change but its efficiency cannot be improved. However, notable thermoelectric effect takes place when two Majorana zero modes are introduced simultaneously. We believe that the findings in this work provide an alternative method for the detection of the zero mode of Majorana bound state.
