Similarly, the complex-valued components of electronic wavefunctions are associated with phase angles, and likewise are responsible for electronic interference, such as exhibited in electron diffraction patterns. The phase of an electronic wavefunction can be externally manipulated via electromagnetic potentials. For instance, the Aharonov-Bohm (AB) effect describes how an electron experiences a phase shift when circulating in the presence of a magnetic field. This particular effect has been utilized to enable quantum computing operations and information storage on multi-spin systems and semiconductor quantum rings, and to increase the efficiency of electron transport in light-harvesting models. An exciton comprises an electron and a hole. The electron and hole wavefunctions both contain spatially varying phases, reflecting the nodal symmetries of the frontier molecular orbitals, the LUMO and HOMO, respectively. This phase variation is evident in the renderings of HOMO and LUMO orbitals that are often produced from molecular electronic structure calculations. This spatially varying phase is responsible for certain excitonic phenomena, such as the strong sensitivity of charge-transfer coupling to intermolecular twist angle in π-stacked homo-dimers. An exciton can also acquire phase during delocalization, whereby the wavefunction oscillates between different exciton basis states. This phase can be formulated within a complex superposition of basis states and is notably distinct from that which characterizes molecular orbital structure. Our approach to generating CVCs utilizes this kind of complex superposition phase. In particular, we leverage a superposition state that arises when certain highly symmetric chromophores are excited with circularly polarized light. As we describe in the following section, the phase associated with this superposition can dress the intermolecular electronic coupling to external chromophores, and thereby yield CVCs.
