Coherence dynamics in light-harvesting complexes with two-colour spectroscopy

Coherence dynamics in light-harvesting complexes with two-colour spectroscopy

We investigate coherent dynamics in the cryptophyte light-harvesting complex Phycocyanin-645 (PC-645). A two-colour four-wave mixing experiment allows us to isolate a coherence pathway and observe its evolution in the absence of other signals. We measured a decoherence time of 540fs for the coherenc...
