Plasmon-Exciton Coupling and Dephasing in Hybrid Au Nanostructure/J-Aggregate Systems
Janak Bhandari, Robert Catuto, Zhumin Zhang +3
The coupling between propagating surface plasmon polaritons (SPPs) in Au nanostructures and the exciton transitions of cyanine dye J-aggregates has been examined using leakage radi…
Elucidating the Synergetic Interplay between Average Intermolecular Coupling and Coupling Disorder in Short-Time Exciton Transfer
Siwei Wang, Guangming Liu, Hsing-Ta Chen
Exciton transport in molecular aggregates is a fundamental process governing the performance of organic optoelectronics and light-harvesting systems. While most theoretical studies…
MQED-QD: An Open-Source Package for Quantum Dynamics Simulation in Complex Dielectric Environments
Guangming Liu, Siwei Wang, Hsing-Ta Chen
Simulating the dynamics of molecular excitons in complex nanophotonic environments requires integrating rigorous electromagnetic simulations with accurate treatments of open quantu…
Robust Surface-Induced Enhancement of Exciton Transport in Magic-Angle-Oriented Molecular Aggregates
Siwei Wang, Liang-Yan Hsu, Hsing-Ta Chen
Exciton transport in molecular aggregates with magic-angle orientation is expected to be strongly suppressed due to their negligible dipole-dipole interactions. However, recent rep…
Dissecting Exciton-Polariton Transport in Organic Molecular Crystals: Emerging Conductivity Assisted by Intermolecular Vibrational Coupling
Guangming Liu, Hsing-Ta Chen
In this work, we systematically investigate the spectral and transport properties of exciton-polaritons under the explicit influence of intermolecular vibrational coupling, which i…
