Disorder-Induced Localization of Molecular Polaritons Despite Spectroscopic Strong Coupling
Amitav Sahu, Tönu Pullerits
Molecular polaritons are hybrid light--matter quasiparticles whose collective character is often associated with molecular excitations extending over many emitters. However, molecu…

Helicity-Resolved Spatiotemporal Mapping of Chiral Plexcitons in Helicoids
Jeong Hyun Han, Sankaran Ramesh, Jaeyeon Jo +10
Plasmon-exciton hybrids, or plexcitons, offer deeply subwavelength light-matter interactions with versatile pathways for energy redistribution. Incorporating chirality into such sy…

Prominent Signatures of Energy Transfer in Action-Detected Spectra of a Cyanobacterial Photosynthetic Protein
Sayan Ghosh, Amitav Sahu, Stephanie Gonzalez-Migoni +2
Action-detected two-dimensional electronic spectroscopy (A-2DES) could potentially be a versatile chemical tool with applicability across a range of photophysical observables such…
