Exciton coupling induces vibronic hyperchromism in light-harvesting complexes
Jan Schulze, Magne Torbjörnsson, Oliver Kühn +1
The recently suggested possibility that weak vibronic transitions can be excitonically enhanced in light-harvesting complexes is studied in detail. A vibronic exciton dimer model w…
Generalized lock-in amplifier for precision measurement of high frequency signals
Siyuan Fu, Atsunori Sakurai, Liang Liu +4
We herein formulate the concept of a generalized lock-in amplifier for the precision measurement of high frequency signals based on digital cavities. Accurate measurement of signal…
Multiple exciton generation in nano-crystals revisited: Consistent calculation of the yield based on pump-probe spectroscopy
Khadga J. Karki, Fei Ma, Kaibo Zheng +7
Multiple exciton generation (MEG) is a process in which more than one exciton is generated upon the absorption of a high energy photon, typically higher than two times the band gap…
Digital Cavities and Their Potential Applications
Khadga Karki, Magne Torbjornsson, Julia. R. Widom +2
The concept of a digital cavity is presented. The functionality of a tunable radio-frequency/microwave cavity with unrestricted Q-factor is implemented. The theoretical aspects of…
