Two-dimensional spectroscopy of open quantum systems
arXiv:2412.10931 · doi:10.1021/acs.jpclett.4c03597
Abstract
Two-dimensional spectroscopy is discussed for open quantum systems with multiple simultaneously measurable fluxes. In particular, we discuss a junction where optical measurements of photon flux are complemented with simultaneous transport measurements of electron currents. Theory of two-dimensional spectroscopy in both fluxes is developed employing non-self-consistent nonequilibrium Green's function formulation. Theoretical derivations are illustrated with numerical simulations within generic junction model.
