"Nanoelectromechanics with spin: effects of resonance scattering and strong electron correlations"

 

 

ABSTRACT:  

 

I will discuss ideas, realizations and applications of nano-electro-mechanical (NEM) devices - the systems implying a strong coupling between the electronic and mechanical degrees of freedom. In this talk I will mostly concentrate on influence of the resonance scattering (Kondo effect) and strong electron correlations on quantum transport through the mobile quantum dot devices. I show that the study of a Kondo-NEM phenomenon provides additional (as compared with standard conductance measurements in a non-mechanical device) information on retardation effects in the formation of a many-particle cloud accompanying the Kondo tunneling. A possibility for superhigh tunability of mechanical dissipation as well as supersensitive detection of mechanical displacement is demonstrated.
