Kondo cloud in a superconductor

CP Moca, I Weymann, MA Werner, G Zaránd - Physical Review Letters, 2021 - APS
Magnetic impurities embedded in a metal are screened by the Kondo effect, signaled by the
formation of an extended correlation cloud, the so-called Kondo or screening cloud. In a …

Transport properties and Kondo correlations in nanostructures: Time-dependent DMRG method applied to quantum dots coupled to Wilson chains

LGGV Dias da Silva, F Heidrich-Meisner… - Physical Review B …, 2008 - APS
We apply the adaptive time-dependent density-matrix renormalization-group method
(tDMRG) to the study of transport properties of quantum-dot systems connected to metallic …

Real-space renormalization group flow in quantum impurity systems: Local moment formation and the Kondo screening cloud

AK Mitchell, M Becker, R Bulla - Physical Review B—Condensed Matter and …, 2011 - APS
The existence of a length scale ξ K∼ 1/TK (with TK the Kondo temperature) has long been
predicted in quantum impurity systems. At low temperatures T≪ TK, the standard …

Kondo screening cloud in the single-impurity Anderson model: A density matrix renormalization group study

A Holzner, IP McCulloch, U Schollwöck, J von Delft… - Physical Review B …, 2009 - APS
A magnetic moment in a metal or in a quantum dot is, at low temperatures, screened by the
conduction electrons through the mechanism of the Kondo effect. This gives rise to spin-spin …

Quench dynamics and relaxation of a spin coupled to interacting leads

H Bragança, MF Cavalcante, RG Pereira, MCO Aguiar - Physical Review B, 2021 - APS
We study a quantum quench in which a magnetic impurity is suddenly coupled to Hubbard
chains, whose low-energy physics is described by Tomonaga-Luttinger liquid theory. Using …

Numerical analysis of the spatial range of the Kondo effect

CA Büsser, GB Martins, L Costa Ribeiro, E Vernek… - Physical Review B …, 2010 - APS
The spatial length of the Kondo screening is still a controversial issue related to Kondo
physics. While renormalization-group and Bethe-Ansatz solutions have provided detailed …

Nonequilibrium spatiotemporal formation of the Kondo screening cloud on a lattice

M Nuss, M Ganahl, E Arrigoni, W von der Linden… - Physical Review B, 2015 - APS
We study the nonequilibrium formation of a spin screening cloud that accompanies the
quenching of a local magnetic moment immersed in a Fermi sea at zero temperature. Based …

Block Lanczos density-matrix renormalization group method for general Anderson impurity models: Application to magnetic impurity problems in graphene

T Shirakawa, S Yunoki - Physical Review B, 2014 - APS
We introduce a block Lanczos (BL) recursive technique to construct quasi-one-dimensional
models, suitable for density-matrix renormalization group (DMRG) calculations, from single …

Resolving the nonequilibrium Kondo singlet in energy-and position-space using quantum measurements

A Erpenbeck, G Cohen - SciPost Physics, 2021 - scipost.org
The Kondo effect, a hallmark of strong correlation physics, is characterized by the formation
of an extended cloud of singlet states around magnetic impurities at low temperatures. While …

IRLM and Kondo Correlations

M Debertolis - Quantum Impurity Problems in the Framework of …, 2024 - Springer
In the previous chapter, we traced the history of dilute magnetic impurities in metals and
quantum dots. The SIAM and Kondo models were presented, originally introduced to …
