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 ...

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 ...

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 ...

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 ...

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 ...

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. ...

We study the Ruderman-Kittel-Kasuya-Yosida interaction in three-dimensional Dirac semimetals. Using retarded Green's functions in real space, we obtain and analyze asymptotic expressions for the interaction, with magnetic ...

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 ...

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 ...
