We use the quantum–classical path integral (QCPI) methodology to report numerically exact,
fully quantum mechanical results for the exciton-vibration dynamics in the …

In photosynthesis, light is harvested and its energy is used to produce the various biological
components that support nearly all life on earth. It is oxygenic photosynthesis that led to the …

Calculating the evolution of an open quantum system ie, a system in contact with a thermal
environment has presented a theoretical and computational challenge for many years …

This Perspective examines how hundreds of pigment molecules in purple bacteria
cooperate through quantum coherence to achieve remarkable light-harvesting efficiency …

Establishing the fundamental chemical principles that govern molecular electronic quantum
decoherence has remained an outstanding challenge. Fundamental questions such as how …

The dynamics of excitation energy transfer within the B850 ring of light harvesting complex 2
from Rhodobacter sphaeroides and between neighboring B850 rings is investigated by …

The optical spectra of photosynthetic pigment–protein complexes usually show broad
absorption bands, often consisting of a number of overlap**,'hidden'bands belonging to …

We report a method for the structure-based calculation of the spectral density of the pigment–
protein coupling in light-harvesting complexes that combines normal-mode analysis with the …

The chromatophore of purple bacteria is an intracellular spherical vesicle that exists in
numerous copies in the cell and that efficiently converts sunlight into ATP synthesis …

Recent evidence of electronic coherence during energy transfer in photosynthetic antenna
complexes has reinvigorated the discussion about whether coherence and/or entanglement …
