Pumping / Stirring Publications
The scope of the 2003-2006 publications was to put
quantum pumping in open systems and quantum stirring in closed systems
under the same umbrella of linear response theory (Kubo). The focus was
on "ring" geometry (either "two barrier" or "piston" systems). In 2008
there are new works that illuminate the physical results using a
heuristic "splitting ratio" approach. The simplest model to clarify the
idea is a 3-site tight-binding system. This approach was also used to
derive some results for the counting statistics. Another direction was
to apply the formalism to Bose condensed particles, and to see what is
the significance of having interactions.
