Interação entre impurezas enterradas em um semimetal de Weyl: caso magnético
(Universidade Estadual Paulista (Unesp), 2019-02-27)
Investigamos teoricamente um sistema composto por duas impurezas afastadas e enterradas em um semimetal de Weyl. Analisamos a densidade de estados local para duas situações: com simetrias de reversão temporal e inversão ...
Interação entre impurezas enterradas em um Semimetal de Weyl: caso não magnético
(Universidade Estadual Paulista (Unesp), 2019-01-14)
Por meio da equação de Weyl que descreve o bulk de um semimetal de Weyl, inserimos duas impurezas no interior deste semimetal, com o intuito de medir a condutância desse sistema por meio de uma ponta de um microscópio de ...
Unveiling a crystalline topological insulator in a Weyl semimetal with time-reversal symmetry
(American Physical Society, 2014-09)
We consider a natural generalization of the lattice model for a periodic array of two layers, A and B , of spinless electrons proposed by Fu [Phys. Rev. Lett. 106, 106802 (2011)] as a prototype for a crystalline insulator. ...
Electronic Transport in Weyl Semimetals with a Uniform Concentration of Torsional Dislocations
(2022)
In this article, we consider a theoretical model for a type I Weyl semimetal, under the presence of a diluted uniform concentration of torsional dislocations. By means of a mathematical analysis for partial wave scattering ...
Thermo-Magneto-Electric Transport through a Torsion Dislocation in a Type I Weyl Semimetal
(2021)
Herein, we study electronic and thermoelectric transport in a type I Weyl semimetal nanojunction, with a torsional dislocation defect, in the presence of an external magnetic field parallel to the dislocation axis. The ...
Espalhamento e interferência eletrônica entre estados induzidos por impurezas em semimetais de Dirac e Weyl
(Universidade Estadual Paulista (Unesp), 2019-07-03)
Embora o estado fundamental de moléculas covalentes diatômicas na natureza seja inevitavelmente ligante com primeiro estado excitado antiligante, foi demonstrado teoricamente que um par de impurezas, colocadas dentro de ...
Multiterminal conductance at the surface of aWeyl semimetal
(2018)
Weyl semimetals are a new paradigmatic topological phase of matter featuring a gapless spectrum. One of its most distinctive features is the presence of Fermi arc surface states. Here, we report on atomistic simulations ...
Electronic transport in strain Weyl semimetals
(2018)
We consider the electronic transport in Weyl semimetals (WSM) due to the superposition of an external magnetic field and mechanical strain. We find exact
analytical solutions for singleparticle
states inside and outside ...

Electronic transport in torsional strained weyl semimetals
(2018)
In a recent paper (Munoz and Soto-Garrido 2017 J. Phys.: Condens. Matter 29 445302) we have studied the effects of mechanical strain and magnetic field on the electronic transport properties in graphene. In this article ...
