Observation of Kondo cloud-coupling in a mirror-symmetric carbon nanotube array-molybdenum structure [PDF]
Nature CommunicationsMagnetic impurities in a non-magnetic metal are screened by conduction electrons, forming a spin cloud known as a Kondo cloud. Experimental detection of this Kondo screening cloud in dilute magnetic alloys remains challenging.

Fractional shot noise of an SU(N) Kondo system [PDF]
Beilstein Journal of NanotechnologyWe consider transport through a multilevel interacting quantum dot (N-QD) in the Kondo regime. Using the Kotliar–Ruckentein slave boson approach (SBMFA) for an N-level Anderson model, we define effectively noninteracting quasiparticles of the SU(N) Kondo
