The overall purpose of the project is to estimate how efficiently devices based on quantum dots can convert thermal energy to electrical energy. Experimental data for this project has already been obtained from low temperature measurements conducted at Solid State Physics.
The aurora resource will be used to analyze this data by fitting it to theoretical calculations and to theoretically investigate weather new geometries can enhance the performance. For the calculations we assume a weak coupling between the dot(s) and its contacts. We expand the equation of motion for the density matrix in this coupling and employ a Master equation approach to calculate the involved currents up to second order. Going to second order includes evaluating a large number of double integrals and the computational power required compared to first order is significantly larger. We are also breaking the temperature symmetry of the contacts which means that these integrals no longer have nice analytical solutions.
