@article{Kloss2019MultisetMP, title={Multiset Matrix Product State Calculations Reveal Mobile Franck-Condon Excitations Under Strong Holstein-Type Coupling.}, author={Benedikt Kloss and David R. Reichman and Roel Tempelaar}, journal={Physical review letters}, year={2019}, volume={123 12}, pages={ 126601 } }

We show that the dynamics of (vertical) Franck-Condon excitations in the regime where Holstein-coupled vibrational modes mix strongly with electronic degrees of freedom sharply contrasts with the known self-localized behavior of vibrationally relaxed excitations. Instead, the strongly coupled modes are found to periodically induce resonances between interacting electronic sites, during which effective excitation transfer occurs, allowing Franck-Condon excitations to attain substantial mean…
