Evolution and universality of two-stage Kondo effect in single manganese phthalocyanine molecule transistors [PDF]

Nature Communications, 2021
The Kondo effect can serve as a powerful paradigm to understand strongly correlated many-body processes in physics. Here, Guo et al. utilize single molecule transistor devices as a testbed to study multi-level Kondo correlation and show electrical gate ...

Dynamically Induced Multi-Channel Kondo Effect [PDF]

Physical Review B, 2000
We study how the multi-channel Kondo effect is dynamically induced to affect the photoemission and the inverse photoemission spectrum when an electron is emitted from (or added to) the completely screened Kondo impurity with spin $S>1/2$.

Kondo-Zeno crossover in the dynamics of a monitored quantum dot [PDF]

Nature Communications
Continuously monitoring a quantum system can strongly affect its properties and even suppress its coherent evolution via the Quantum Zeno effect. Here we focus on one of the simplest entangled many-body state, arising via the Kondo effect in a strongly ...

Surface Kondo effect and non-trivial metallic state of the Kondo insulator YbB12 [PDF]

Nature Communications, 2016
Topological state in Kondo insulators has been provoked in SmB6, but the origin of surface states and topological order remain elusive. Here, Hagiwara et al.

Multichannel Topological Kondo Effect

Physical Review Letters, 2023
A Coulomb blockaded $M$-Majorana island coupled to normal metal leads realizes a novel type of Kondo effect where the effective impurity "spin" transforms under the orthogonal group $SO(M)$. The impurity spin stems from the non-local topological ground state degeneracy of the island and thus the effect is known as the topological Kondo effect.
