Trapped-Ion Simulation of Molecular Electron Transfer

ORAL

Abstract

The properties of trapped ions make them a pristine platform for simulating the quantum dynamics of spin [1] and spin-boson [2] systems. In this work [3], we experimentally simulate molecular charge transfer processes from a donor state to an acceptor state governed by the open-system dynamics using a pair of trapped 171Yb+ and 172Yb+ ions. Using the 2S1/2 – 2D3/2 optical transition of 172Yb+ ion for sympathetic cooling, we engineer the phonon bath that is coupled to the donor and acceptor states encoded by the spin states of the 171Yb+ ion via coherent spin-phonon drive. By tuning the donor-acceptor energy difference, their coupling, and the bath properties, we study the transfer dynamics in the quantum resonant diabatic and adiabatic regimes [4]. Our results provide a testing ground for models of molecular charge transfer processes paving the way for the design and development of efficient bioenergetics and molecular electronics.
