Background-free measurement of exciton-exciton annihilation by two-quantum fluorescence-detected pump-probe spectroscopy
Ajay Jayachandran, Stefan Mueller, Christoph Lambert +1
We introduce two-quantum (2Q) fluorescence-detected pump-probe (F-PP) spectroscopy as a tool to probe ultrafast multiparticle interactions in many-body systems. We describe a pulse…
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…
Separating orders of response in transient absorption and coherent multi-dimensional spectroscopy by intensity variation
Jacob J. Krich, Luisa Brenneis, Peter A. Rose +5
Interpretation of time-resolved spectroscopies such as transient absorption (TA) or two-dimensional (2D) spectroscopy often relies on the perturbative description of light-matter i…
Plasmonic Su-Schrieffer-Heeger chains with strong coupling amplitudes
Benedikt Schurr, Matthias Hensen, Luisa Brenneis +6
Plasmonic many-particle systems with precisely tuned resonances and coupling strengths can exhibit emergent collective properties governed by universal principles. In one-dimension…
Cogwheel phase cycling in population-detected optical coherent multidimensional spectroscopy
Ajay Jayachandran, Stefan Mueller, Tobias Brixner
An integral procedure in every coherent multidimensional spectroscopy experiment is to suppress undesired background signals. For that purpose, one can employ a particular phase-ma…
