This Jaynes-Cummings-Leads (JCL) model makes possible that the fermion current through the dot creates a photon flux, which describes a light-emitting device. The same model also describes a transformation of the photon flux into a fermion current, i.e. a quantum dot light-absorbing device. The key tool to obtain these results is an abstract Landauer-Büttiker formula.application/pdfeng510Landauer-Büttiker formulaJaynes-Cummings modelcoupling to leadslight emissionsolar cellsReport
