Fine structure in cotunneling spectroscopy<br />
Jens Paaske, University of Copenhagen, Denmark<br />
Cotunneling through Coulomb blockaded nano-transistors provides an informative<br />
spectroscopy of the system bridging source and drain contacts. In this<br />
talk, I address the question to what extent this transport probe can also tell<br />
us more about the spin-orbit coupling in the dot, tube, wire or molecule un<strong>der</strong><br />
scrutiny. From inelastic cotunneling spectroscopy, one might directly observe<br />
avoided crossings between spin-orbit coupled states, but there are also a<br />
number of more subtle clues to be picked up. What happens to the Kondo<br />
resonances, reflecting the “flippable” degeneracies in the system, what are the<br />
effects on tunneling induced level renormalization, and to what extent have<br />
we already observed some of this spectroscopic fine structure experimentally?<br />
