Franson-Interferometric Bounds on Entangled Two-Photon Absorption
Albin Hedse, Sankaran Ramesh, Luis Matheis +7
Entangled photons offer quantum correlations with no classical analogue. In entangled pair two-photon absorption (ETPA), absorption rate is predicted to scale linearly rather than…
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…
Low and High Frequency Vibrations Synergistically Enhance Singlet Exciton Fission Through Robust Vibronic Resonances
Atandrita Bhattacharyya, Amitav Sahu, Sanjoy Patra +1
Singlet exciton fission (SEF) is initiated by ultrafast internal conversion of a singlet exciton into a correlated triplet pair (TT)1. The `reaction coordinates' for ultrafast SEF…
Coherence Transfer and Destructive Interference in Two-Dimensional Coherence Maps
Amitav Sahu, Vivek Tiwari
Coherence maps (CMs) in multidimensional spectroscopy report total interference of all quantum coherent pathways. Detailed understanding of how this interference manifests spectros…
High-sensitivity Fluorescence-Detected Multidimensional Electronic Spectroscopy Through Continuous Pump-probe Delay Scan
Amitav Sahu, Vivek N. Bhat, Sanjoy Patra +1
Background-free fluorescence detection in multidimensional electronic spectroscopy promises high sensitivity compared to conventional approaches. Here we explore the sensitivity li…
Trap Mediated Energy Transport via Vibronic Resonance
Sanjoy Patra, Amitav Sahu, Vivek Tiwari
Controlling energy transfer through vibronic resonance is an interesting possibility. Exact treatment of non-adiabatic vibronic coupling is necessary to fully capture its role in d…
Resonant Vibrational-Electronic Coupling between Photosynthetic Excitons is Inadequately Described by Reduced Basis Sets
Amitav Sahu, Jo Sony Kurian, Vivek Tiwari
Vibrational-electronic (vibronic) resonance and its role in energy and charge transfer has been experimentally and theoretically investigated in several photosynthetic proteins. Us…
