# Momentum relaxation in a holographic Weyl semimetal

@article{Zhao2021MomentumRI, title={Momentum relaxation in a holographic Weyl semimetal}, author={Junkun Zhao}, journal={Physical Review D}, year={2021} }

We study the effects of momentum relaxation on the holographic Weyl semimetal which exhibits a topological quantum phase transition between the Weyl semimetal phase and a topological trivial phase. The conservation of momentum in the field theory is broken by the axion fields in holography. The topological Weyl semimetal phase is characterized by a nontrivial anomalous Hall conductivity. We find that the critical value of the phase transition decreases when we increase the momentum relaxation… Expand
