Molecules and Chromophore Aggregate Systems

In this theme, we aim to: (i) understand how symmetry breaking in molecules impacts vibronic coherence; (ii) probe the role of coherent exciton motion in the subsequent production of spin-coherent electron-hole pairs; (iii) elucidate ratcheting schemes, guided by theory, that enable direct coherent, lossless flow of energy; (iv) examine how spin delocalization in an extended p systems controls spin coherence; (v) explore, using theory and experiment, how coherent electronic superposition states carrying angular momentum may impact charge transfer quantum dynamics.
