Journal ArticleDOI
Local detection of electromagnetic energy transport below the diffraction limit in metal nanoparticle plasmon waveguides.
Stefan A. Maier,Pieter G. Kik,Harry A. Atwater,Sheffer Meltzer,Elad Harel,Bruce E. Koel,Ari A.G. Requicha +6 more
TL;DR: Observations of electromagnetic energy transport from a localized subwavelength source to a localized detector over distances of about 0.5 μm in plasmon waveguides consisting of closely spaced silver rods are presented.
Journal ArticleDOI
Long-lived quantum coherence in photosynthetic complexes at physiological temperature
Gitt Panitchayangkoon,Dugan Hayes,Kelly A. Fransted,Justin R. Caram,Elad Harel,Jianzhong Wen,Robert E. Blankenship,Gregory S. Engel +7 more
TL;DR: Evidence that quantum coherence survives in FMO at physiological temperature for at least 300 fs, long enough to impact biological energy transport is presented, proving that the wave-like energy transfer process discovered at 77 K is directly relevant to biological function.
Journal ArticleDOI
Quantum coherence spectroscopy reveals complex dynamics in bacterial light-harvesting complex 2 (LH2)
Elad Harel,Gregory S. Engel +1 more
TL;DR: This work provides experimental evidence of long-lived quantum coherence between the spectrally separated B800 and B850 rings of the light-harvesting complex 2 (LH2) of purple bacteria and suggests that quantum mechanical interference between different energy transfer pathways may be important even at ambient temperature.
PatentDOI
Real-time mapping of electronic structure with single-shot two-dimensional electronic spectroscopy
Elad Harel,Gregory S. Engel +1 more
TL;DR: In this paper, a line within a portion of the sample with four laser pulses is illuminated, where along the entire line the difference in the arrival times between two of the laser pulses varies as a function of the position and the difference between the other two pulses is constant along the whole line.
Journal ArticleDOI
Cation Engineering in Two-Dimensional Ruddlesden-Popper Lead Iodide Perovskites with Mixed Large A-Site Cations in the Cages.
Yongping Fu,Xinyi Jiang,Xiaotong Li,Boubacar Traore,Ioannis Spanopoulos,Claudine Katan,Jacky Even,Mercouri G. Kanatzidis,Elad Harel +8 more
TL;DR: A series of cation engineered 2D Ruddlesden-Popper lead iodide perovskites are reported by incorporating large EA cation in the cage and it is found that such structural deformation leads to a blue-shifted bandgap, sub-bandgap trap states with wider energetic distribution, and stronger photoluminescence quenching.
