Excited-state relaxations in molecules are responsible for a red shift of the absorption peak with respect to the emission peak (Franck-Condon shift). The magnitude of this shift in semiconductor quantum dots is still unknown. Here we report first-principle calculations of excited-state relaxations in small (diameter ≤ 2.2 nm) Si nanocrystals, showing that the Franck-Condon shift is surprisingl...

Franck-Condon effects associated with intervalence excitation of the Creutz-Taube ion (a prototypical delocalized mixed-valency system) have been evaluated via a time-dependent analysis of resonance Raman scattering intensities and the intervalence absorption lineshape. Quantitative studies in the extended near infrared (1320 nm excitation) revealed that at least eight, and possibly nine, vibra...

The celebrated Franck-Hertz experiment is reinterpreted by analogy with the Glimmentladung experiment, formerly performed by Heinrich Hertz.

The optical absorption of the Fröhlich polaron model is obtained by an approximation-free diagrammatic Monte Carlo method and compared with two new approximate approaches that treat lattice relaxation effects in different ways. We show that: (i) a strong coupling expansion, based on the Franck-Condon principle, well describes the optical conductivity for large coupling strengths (alpha > 10); (...

We show that Franck-Condon physics leads to a significant current suppression at low bias voltages (termed Franck-Condon blockade) in transport through single molecules with strong coupling between electronic and vibrational degrees of freedom. Transport in this regime is characterized by remarkably large Fano factors (10(2)-10(3) for realistic parameters), which arise due to avalanchelike tran...
