摘要:
We theoretically study thermoelectric transport through a quantum dot coupled to two side quantum dots in the linear response regime by the nonequilibrium Green's function technique. Our results show that thermoelectric properties are strongly influenced by the Dicke effect. At low temperature, for small (very large) level shift and large interdot coupling the subradiant state contributes a sharp peak to the Dicke spectral line in the electrical and thermal conductance spectrum and leads to a st ...More
