摘要：
We present a theoretical analysis of a possible route for directly detecting Kondo resonances in local density of states (LDOS) of an interacting quantum dot. By very weakly coupling a third and/or a fourth lead to a two-probe quantum dot and measuring differential conductance through these extra links, we show that Kondo peaks directly map onto the differential conductance measured from the third link. We analyze the conditions by which this detection of, Kondo peaks in LDOS is possible.
