Double-excitation manifold's effect on exciton transfer dynamics and the efficiency of coherent light harvesting
Zixuan Hu, Gregory S. Engel, Sabre Kais
The efficiency of natural light harvesting systems is largely determined by their ability to transfer excitations from the antenna to the energy trapping center before recombinatio…
Dark states and delocalization: competing effects of quantum coherence on the efficiency of light harvesting systems
Zixuan Hu, Gregory S. Engel, Fahhad H. Alharbi +1
Natural light harvesting systems exploit electronic coupling of identical chromophores to generate efficient and robust excitation transfer and conversion. Dark states created by s…
Accessing dark states optically through excitation-ferrying states
Zixuan Hu, Gregory S. Engel, Sabre Kais
The efficiency of solar energy harvesting systems is largely determined by their ability to transfer excitations from the antenna to the energy trapping center before recombination…
A direct basis approach to nonorthogonality in second quantization. Theory and application
Zixuan Hu, Mark A. Ratner, Tamar Seideman
We present a direct basis formalism for using nonorthogonal basis sets in the second quantization framework. As an alternative to the dual basis formalism, a direct basis retains t…
