Robustness of RKKY interactions across a Weyl node-annihilation transition
João V. F. Alves, Joelson F. Silva, Luis G. G. V. Dias da Silva
Weyl semimetals (WSMs), with their unique topological properties and distinct electronic structure, exhibit intriguing properties when either time-reversal or inversion symmetries…
Multi-Dirac and Weyl physics in heavy-fermion systems
Joelson F. Silva, E. Miranda
We have studied multi-Dirac/Weyl systems with arbitrary topological charge n in the presence of a lattice of local magnetic moments. To do so, we propose a multi-Dirac/Weyl Kondo l…
Kondo screening regimes in multi-Dirac and Weyl systems
G. T. D. Pedrosa, Joelson F. Silva, E. Vernek
We have investigated the Kondo physics of a single magnetic impurity embedded in multi-Dirac (Weyl) node fermionic systems. By using a generic effective model for the host material…
Robustness of the Kondo effect in a quantum dot coupled to Majorana zero modes
Joelson F. Silva, Luis G. G. V. Dias da Silva, E. Vernek
The prospect of using semiconductor quantum dots as an experimental tool to distinguish Majorana zero modes (MZMs) from other zero-energy excitations such as Kondo resonances has b…
Modified exchange interaction between magnetic impurities in spin-orbit coupled quantum wires
Joelson F. Silva, E. Vernek
Indirect exchange interaction between magnetic impurities in one dimensional systems is a matter of long discussions since Kittel has established that in the asymptotic limit it de…
Kondo effect in a quantum wire with spin-orbit coupling
G. R. de Sousa, Joelson F. Silva, E. Vernek
The influence of spin-orbit interactions on the Kondo effect has been under debate recently. Studies conducted recently on a system composed by an Anderson impurity on a 2DEG with…
Andreev and Majorana bound states in single and double quantum dot structures
Joelson F. Silva, E. Vernek
We present a numerical study of the emergence of Majorana and Andreev bound states in a system composed by two quantum dots, in which one of then is coupled to a conventional super…
