Two-Dimensional Spectroscopy of Open Quantum Systems: Nonequilibrium Green’s Function Formulation
Two-dimensional spectroscopy is examined for open quantum systems featuring multiple simultaneously measurable fluxes. Specifically, we explore a junction where optical measurements of photon flux are paired with concurrent transport measurements of electron currents. The theory of two-dimensional spectroscopy for both fluxes is developed using a nonself-consistent nonequilibrium Green's function formulation. Theoretical derivations are demonstrated through numerical simulations within a generic junction model.
