FROM THE ADIABATIC TO THE ANTI-ADIABATIC REGIMESOF PHONON-ASSISTED TUNNELING

<font face="Verdana"> </font> <p style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px" align="justify">The promise of molecular electronics has generated intense interest in the interplay of molecular vibrations and resonant electronic transport. Two customary limits of phonon-assisted tunneling are the adiabatic and anti-adiabatic regimes, where the phonon frequency is either sufficiently large or sufficiently small as compared to the bare electronic hopping rate. In the former case the phonon can efficiently respond to hopping events by forming a polaron, thus suppressing the bare tunneling rate. In the latter case the phonon is too slow to track the electronic motion, having little effect on its rate. I will present a systematic study of the crossover between the two regimes in the framework of the resonant-level model. Emphasis will be put on the physical parameters governing the transition, its manifestations in linear transport, and the evolution of the low-energy scale.<font color="#697da9"><span style="FONT-WEIGHT: 700"><a style="TEXT-DECORATION: none" href="https://www.hit.ac.il/fliers.2008-2009/schiller.19.may.2009.pdf" target="_blank"><font color="#697da9"> </a><a href="http://sciences.hit.ac.il/events/ps/fliers.2008-2009/schiller.19.may.2009.pdf" target="_blank">Get the flier...</a></font></span></font></p><SPAN STYLE="display: none"> <P>Acetylenide minutes, pointedly?
