Coherence spectroscopy in dissipative media: A Liouville space pathway approach

摘要: We address the possibility of using coherent control tools to extract useful information about interaction a system with dissipative environment. To that end we extend previous work, which developed coherence spectroscopy based on two-pathway excitation phase control, from isolated molecule limit dense media. Specifically, explore properties channel phase, an observable energy-domain experiments was shown in carry material system. Our analysis is combination steady state and time-dependent analytical perturbative approaches within density matrix formalism, complemented by nonperturbative numerical simulations. find carries significantly richer presence decoherence mechanisms than their absence. In particular, rescattering events structured continuum introduce new features spectrum, whose structure conveys both molecular bath interaction.
