      abstract     = {Photosystem II (PSII) reaction center (RC) is a unique
                      complex that is capable of efficiently separating electronic
                      charges across the membrane. The primary energy- and
                      charge-transfer (CT) processes occur on comparable ultrafast
                      timescales, which makes it extremely challenging to
                      understand the fundamental mechanism responsible for the
                      near-unity quantum efficiency of the transfer. Here, we
                      elucidate the role of quantum coherences in the ultrafast
                      energy and CT in the PSII RC by performing two-dimensional
                      (2D) electronic spectroscopy at the cryogenic temperature of
                      20 kelvin, which captures the distinct underlying quantum
                      coherences. Specifically, we uncover the electronic and
                      vibrational coherences along with their lifetimes during the
                      primary ultrafast processes of energy and CT. We construct
                      an excitonic model that provides evidence for coherent
                      energy and CT at low temperature in the 2D electronic
                      spectra. The principles could provide valuable guidelines
                      for creating artificial photosystems with exploitation of
                      system-bath coupling and control of coherences to optimize
                      the photon conversion efficiency to specific functions.},
