容简介:


The Kondo effect is a long-standing paradigmatic many-body problem in condensed matter physics. The recent progresses in nanoscience and technology has further made possible new realizations of exotic Kondo physics. In this talk, I will discuss some experimental aspects of (1) the standard Kondo effect due to the existence of isolated localized spin-half magnetic moments, and (2) the two-impurity Kondo effect featured quantum critical behaviors of the transport properties. (3) I will briefly discuss our observation of nonmagnetic Kondo effect due to two-level tunneling systems. In this case, the Kondo physics originates from the coupling of the electronic orbital wavefunctions with dynamical structural defects.
