Kondo interaction in FeTe and its potential role in the magnetic order

open access: yesNature Communications, 2023
Finding d-electron heavy fermion states has been an important topic as the diversity in d-electron materials can lead to many exotic Kondo effect-related phenomena or new states of matter such as correlation-driven topological Kondo insulator.

Kondo effect in carbon nanotube quantum dots with spin-orbit coupling [PDF]

open access: yes, 2008
Motivated by recent experimental observation of spin-orbit coupling in carbon nanotube quantum dots [F. Kuemmeth \textsl{et al.}, Nature (London) {\bf 452}, 448 (2008)], we investigate in detail its influence on the Kondo effect.

Exotic Kondo Effect from Magnetic Trimers [PDF]

open access: yesPhysical Review Letters, 2005
Motivated by the recent experiments of Jamneala {\em et al.} [T. Jamnaela {\em et al.}, Phys. Rev. Lett. {\bf 87}, 256804 (2001)], by combining {\em ab-initio} and renormalization group methods, we study the strongly correlated state of a Cr trimer deposited on gold. Internal orbital fluctuations of the trimer lead to huge increase of $T_K$ compared to

Topological Kondo Effect with Majorana Fermions [PDF]

open access: yesPhysical Review Letters, 2012
The Kondo effect is a striking consequence of the coupling of itinerant electrons to a quantum spin with degenerate energy levels. While degeneracies are commonly thought to arise from symmetries or fine-tuning of parameters, the recent emergence of Majorana fermions has brought to the fore an entirely different possibility: a "topological degeneracy ...

Two-dimensional heavy fermion in a monoatomic-layer Kondo lattice YbCu2

open access: yesNature Communications, 2023
The Kondo effect between localized f-electrons and conductive carriers leads to exotic physical phenomena. Among them, heavy-fermion (HF) systems, in which massive effective carriers appear due to the Kondo effect, have fascinated many researchers ...

Topological symplectic Kondo effect

open access: yesPhysical Review B, 2023
Multiple conduction channels interacting with a quantum impurity -- a spin in the conventional ``multi-channel Kondo effect'' or a topological mesoscopic device (``topological Kondo effect'') -- has been proposed as a platform to realize anyonic quasi-particles.

Vibration-mediated Kondo transport in molecular junctions: conductance evolution during mechanical stretching

open access: yesBeilstein Journal of Nanotechnology, 2015
The vibration-mediated Kondo effect attracted considerable theoretical interest during the last decade. However, due to lack of extensive experimental demonstrations, the fine details of the phenomenon were not addressed.

Orbital selective Kondo effect in heavy fermion superconductor UTe2

open access: yesnpj Quantum Materials, 2022
Heavy fermion systems emerge from the collective Kondo effect, and their superconductivity can serve as a promising platform for realizing next-generation quantum technologies.

Band Polarization Effect on the Kondo State in a Zigzag Silicene Nanoribbon

open access: yesNanomaterials, 2022
Using the Numerical Renormalization Group method, we study the properties of a quantum impurity coupled to a zigzag silicene nanoribbon (ZSNR) that is subjected to the action of a magnetic field applied in a generic direction.
