Size Dependence In The Disordered Kondo Problem

, 1996
We study here the role randomly-placed non-magnetic scatterers play on the Kondo effect. We show that spin relaxation effects (with time $\tau_s^o$)in the vertex corrections to the Kondo self-energy lead to an exact cancellation of the singular ...

Kondo screening in Co adatoms with full Coulomb interaction

Physical Review Research, 2020
Using a numerically exact first-principles many-body approach, we revisit the “prototypical” Kondo case of a cobalt impurity on copper. Even though this is considered a well understood example of the Kondo effect, we reveal an unexpectedly strong ...

Kondo Effect of a Magnetic Ion Vibrating in a Harmonic Potential

, 2011
To discuss Kondo effects of a magnetic ion vibrating in the sea of conduction electrons, a generalized Anderson model is derived. The model includes a new channel of hybridization associated with phonon emission or absorption. In the simplest case of the

Dirac fermions and Kondo effect

, 2015
In this study, we investigate the Kondo effect induced by the s-d interaction where the conduction bands are occupied by Dirac fermions. The Dirac fermion has the linear dispersion and is described typically by the Hamiltonian such as $H_k= v{\bf k}\cdot

Emergence of Kondo-assisted Néel order in a Kondo necklace model

Communications Materials
The interplay between Kondo screening and magnetic order has long been a central issue in the physics of strongly correlated systems. While the Kondo effect has traditionally been understood to suppress magnetism through the formation of local singlets ...

Additional energy scale in SmB6 at low-temperature

Nature Communications, 2016
Many discrepancies exist to question the nature of the candidate topological Kondo insulator, SmB6. Here, Jiao et al. observe in-gap states on well characterized (001) surfaces of SmB6, indicating a suppression of the Kondo effect at surface, which ...

Impact of Majorana fermions on the Kondo state in the carbon nanotube quantum dot

Journal of Physics Communications
We have studied the quantum conductance of the Kondo state in the carbon nanotube quantum dot (CNTQD) with side-attached multi-Majorana fermion states in topological superconductors (TSCs).

Correlation Effects in Side-Coupled Quantum Dots

, 2007
Using Wilson's numerical renormalization group (NRG) technique we compute zero-bias conductance and various correlation functions of a double quantum dot (DQD) system. We present different regimes within a phase diagram of the DQD system.
