Abstract: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. The efect 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 profles of the corresponding molecular orbitals and their spin polarizations
are defned by the relative orientation of the lines connecting two Weyl nodes and two impurities. The
magnetic character of the molecular orbitals and their tunability open the way for using doped Weyl
semimetals for spintronics and realization of qubits.
