High-Order Response Functions with Duschinsky Coupling and Finite Temperature: Application to Two-Dimensional Resonance Raman Spectroscopy
Luca Nils Philipp, Tomislav BeguÅ¡iÄ, Tomislav Begušić
In this work, we derive closed-form expressions for multi-time correlation functions underlying higher-order nonlinear spectroscopic response functions within the harmonic approxim…
Disorder-induced Dark States Line Shape in Pump-Probe Spectroscopy of Polaritons
Luca Nils Philipp, Julian Lüttig, Roland MitriÄ
The formation of hybrid light--matter states called polaritons provides a route to shape the photophysics and photochemistry of molecules. Accordingly, the dynamics of polaritons f…
Exciton-Exciton and Exciton-Photon Annihilation in Polaritonic Systems
Luca Nils Philipp, Julian Lüttig, Roland Mitric
Strong light--matter interactions forming hybrid quasiparticles termed polaritons can specifically tailor molecular photophysics. In this spirit, enhancing energy transport has rec…
Competing excitonic couplings as origin of mimicked phase transitions in zinc-phthalocyanine single crystals
Lisa Schraut-May, Sebastian Hammer, Luca Nils Philipp +9
The optical properties of molecular crystals are largely determined by the excitonic coupling of neighboring molecules. This coupling is extremely sensitive to the arrangement of a…
Probing plexciton dynamics with higher-order spectroscopy
Simon Büttner, Luca Nils Philipp, Julian Lüttig +5
Coupling molecular transition dipole moments to surface-plasmon polaritons (SPPs) results in the formation of new optical quasiparticles, i.e., plexcitons. Mixing the specific prop…
Lineshapes in Pump-Probe Spectroscopy of Polaritons
Luca Nils Philipp, Eva Münzel, Julian Lüttig +1
Forming new hybrid quasiparticles by strong light-matter coupling is a promising tool for tailoring photophysics and photochemistry of molecules. Thus, the ultrafast dynamics of po…
