The physics of Kondo impurities in graphene

L Fritz, M Vojta - Reports on Progress in Physics, 2013 - iopscience.iop.org
This article summarizes our understanding of the Kondo effect in graphene, primarily from a
theoretical perspective. We shall describe different ways to create magnetic moments in …

A Josephson phase battery

E Strambini, A Iorio, O Durante, R Citro… - Nature …, 2020 - nature.com
A classical battery converts chemical energy into a persistent voltage bias that can power
electronic circuits. Similarly, a phase battery is a quantum device that provides a persistent …

Thermometry of strongly correlated fermionic quantum systems using impurity probes

G Mihailescu, S Campbell, AK Mitchell - Physical Review A, 2023 - APS
We study quantum-impurity models as a platform for quantum thermometry. A single
quantum spin-1 2 impurity is coupled to an explicit, structured, fermionic thermal sample …

R Requist, PP Baruselli, A Smogunov… - Nature …, 2016 - nature.com
Scanning tunnelling microscopy and break-junction experiments realize metallic and
molecular nanocontacts that act as ideal one-dimensional channels between macroscopic …

Non-abelian symmetries in tensor networks: A quantum symmetry space approach

A Weichselbaum - Annals of Physics, 2012 - Elsevier
A general framework for non-abelian symmetries is presented for matrix-product and tensor-
network states in the presence of well-defined orthonormal local as well as effective basis …

Switching of a coupled spin pair in a single-molecule junction

S Wagner, F Kisslinger, S Ballmann, F Schramm… - Nature …, 2013 - nature.com
Single-molecule spintronics investigates electron transport through magnetic molecules that
have an internal spin degree of freedom. To understand and control these individual …

Orbitally controlled Kondo effect of Co adatoms on graphene

TO Wehling, AV Balatsky, MI Katsnelson… - Physical Review B …, 2010 - APS
Based on ab initio calculations we identify possible scenarios for the Kondo effect due to Co
adatoms on graphene. General symmetry arguments show that for magnetic atoms in high …

Kondo effect in twisted bilayer graphene

AS Shankar, DO Oriekhov, AK Mitchell, L Fritz - Physical Review B, 2023 - APS
The emergence of flat bands in twisted bilayer graphene at the magic angle can be
understood in terms of a vanishing Fermi velocity of the Dirac cone. This is associated with …

Observation of the underscreened Kondo effect in a molecular transistor

N Roch, S Florens, TA Costi, W Wernsdorfer… - Physical review letters, 2009 - APS
We present the first quantitative experimental evidence for the underscreened Kondo effect,
an incomplete compensation of a quantized magnetic moment by conduction electrons, as …

Computing local multipoint correlators using the numerical renormalization group

SSB Lee, FB Kugler, J von Delft - Physical Review X, 2021 - APS
Local three-and four-point correlators yield important insight into strongly correlated systems
and have many applications. However, the nonperturbative, accurate computation of …
