Sublattice symmetry breaking and Kondo-effect enhancement in strained graphene
Dawei Zhai, Kevin Ingersent, Sergio E. Ulloa +1
Kondo physics in doped monolayer graphene is predicted to exhibit unusual features due to the linear vanishing of the pristine material's density of states at the Dirac point. Desp…
Strained fold assisted transport in graphene systems
R. Carrillo-Bastos, C. León, D. Faria +3
Deformations in graphene systems are central elements in the novel field of {\it straintronics}. Various strain geometries have been proposed to produce specific properties but the…
RKKY interaction and intervalley processes in p-doped transition metal dichalcogenides
D. Mastrogiuseppe, N. Sandler, S. Ulloa
We study the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in p-doped transition metal dichalcogenides such as MoS and WS. We consider magnetic impurities hybridized to…
Gaussian deformations in graphene ribbons: flowers and confinement
R. Carrillo-Bastos, D. Faria, A. Latgé +2
The coupling of geometrical and electronic properties is a promising venue to engineer conduction properties in graphene. Confinement added to strain allows for interplay of differ…
Currents and pseudomagnetic fields in strained graphene rings
D. Faria, A. Latge, S. E. Ulloa +1
We study the effects of strain on the electronic properties and persistent current characteristics of a graphene ring using the Dirac representation. For a slightly deformed graphe…
Kondo regime in triangular arrangements of quantum dots: Molecular orbitals, interference and contact effects
E. Vernek, C. A. Busser, G. B. Martins +3
Transport properties of an interacting triple quantum dot system coupled to three leads in a triangular geometry has been studied in the Kondo regime. Applying mean-field finite-U…
Fractional quantum Hall junctions and two-channel Kondo models
N. Sandler, E. Fradkin
A mapping between fractional quantum Hall (FQH) junctions and the two-channel Kondo model is presented. We discuss in detail this relation for the particular case of a junction of…
