Quantum dot Josephson junctions in the Kondo regime [PDF]
, 2010 In this thesis, we study quantum dots (QD) fabricated from single-wall carbon nanotubes (SWCNT). The SWCNT are connected to source (S) and drain (D) leads by tunnelling contacts whose transparency is characterized by their respective coupling parameters,

Kondo effect with Wilson fermions
, 2021 We investigate the Kondo effect with Wilson fermions. This is based on a mean-field approach for the chiral Gross-Neveu model including four-point interactions between a light Wilson fermion and a heavy fermion.

Molecular Kondo effect in flat-band lattices [PDF]
, 2018 The Kondo effect of a single magnetic impurity embedded in the Lieb lattice is studied by the numerical renormalization group. When the band flatness is present in the local density of states at the impurity site, it quenches the participation of all ...

From four- to two-channel Kondo effect in junctions of XY spin chains
Nuclear Physics B, 2016 We consider the Kondo effect in Y-junctions of anisotropic XY models in an applied magnetic field along the critical lines characterized by a gapless excitation spectrum.

Magnetism and Kondo Effect in Cerium and Uranium Compounds [PDF]
, 2008 A brief review of the Kondo lattice problem is presented, with a special emphasis on the underscreened Kondo effect in ferromagnetic-Kondo uranium compounds and on the spin glass-Kondo competition in disordered heavy fermion cerium ...

Universal scaling of tunable Yu-Shiba-Rusinov states across the quantum phase transition
Communications Physics, 2023 Quantum magnetic impurities give rise to a wealth of phenomena attracting tremendous research interest in recent years. On a normal metal, magnetic impurities generate the correlation-driven Kondo effect.

Resolving the nonequilibrium Kondo singlet in energy- and position-space using quantum measurements
SciPost Physics, 2021 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 many implications of the Kondo cloud's existence have been verified,

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

Angewandte Chemie, EarlyView.Here, we introduce a molecular design principle that fundamentally expands the bottom‐up synthesis of single‐atom catalysts (SACs). Coordinatively flexible polypyridyl units enable bottom‐up formation of ordered carbonaceous frameworks containing atomically dispersed Ru (∼11 wt%) by simple carbonization.
