‘Chiral magnetic chemical bonds in molecular states of impurities in Weyl semimetals’
Abstract: In this seminar, I will talk about our last work wherein we demonstrate that chirality of the electron scattering in Weyl semimetals leads to the formation of magnetic chemical bonds for molecular states of a pair of impurities. This effect is associated with the presence of time-reversal symmetry breaking terms in the Hamiltonian which drive a crossover from s- to p-wave scattering. The profiles of the corresponding molecular orbitals and their spin polarizations are defined by the relative orientation of the lines connecting two Weyl nodes and two impurities. In this sense, doped Weyl semimetals might open a way to investigate the relation between the electronic scattering and spin texture, in which the chiral magnetic behavior is the key.
