Journal ArticleDOI
The formulation of quantum statistical mechanics based on the Feynman path centroid density. II. Dynamical properties
Jianshu Cao,Gregory A. Voth +1 more
TL;DR: In this paper, the centroid-based approach to equilibrium properties developed in the companion paper is outlined and an intriguing quasiclassical role for the path centroid variable in real time position correlation functions is identified.
Journal ArticleDOI
The formulation of quantum statistical mechanics based on the Feynman path centroid density. IV. Algorithms for centroid molecular dynamics
Jianshu Cao,Gregory A. Voth +1 more
TL;DR: In this paper, the centroid molecular dynamics (centroid MD) method is used to calculate dynamical time correlation functions for general many-body quantum systems and a more efficient, but approximate, scheme is devised which is based on the locally optimized harmonic approximation for centroid potential.
Journal ArticleDOI
Optimization of Exciton Trapping in Energy Transfer Processes
Jianshu Cao,Robert J. Silbey +1 more
TL;DR: Though these results are obtained for simple model systems, the physics thus derived provides insights into the working of light harvesting systems, and the approaches developed apply to large-scale computation.

TL;DR: It is demonstrated that interexciton coherences are too short lived to have any functional significance in photosynthetic energy transfer and this work revise the interpretation of coherence signals in photosynthesis systems and leads to a more detailed understanding of the quantum aspects of dissipation.
Journal ArticleDOI
Efficient energy transfer in light-harvesting systems, I: optimal temperature, reorganization energy and spatial–temporal correlations
TL;DR: In this article, the authors use the generalized Bloch-Redfield (GBR) equation approach to correctly describe dissipative exciton dynamics, and find that maximal energy transfer efficiency can be achieved under various physical conditions, including temperature, reorganization energy and spatial-temporal correlations in noise.
