"Single-molecule transistors - A new perspective on the 
Anderson-Holstein model"


Abstract

Following up on a long-standing suggestion by Aviram and Ratner, 
experimenters have recently made great efforts in contacting and gating 
single molecules.  Such experiments pose new theoretical challenges not 
only because typical energy and length scales are different from those 
in conventional nanostructures such as quantum dots, but also because 
they involve degrees of freedom specific to molecular structures such 
as discrete vibrational modes or localized spins.  In this talk, I will 
discuss several situations where the coupling to vibrational modes is 
predicted to dramatically affect the transport properties.  
Specifically, I will show that electron-vibron coupling can induce 
self-similar avalanche transport as well astunneling of electron pairs.
