Abstract

Most of the previously suggested scenarios for the realization of Weyl semimetal on a pyrochlore lattice require breaking of time-reversal symmetry. In this study the authors show that spontaneous deformations of the crystal that break the inversion symmetry can stabilize this phase as well. They demonstrate that in the temperature-elasticity phase diagram Weyl semimetal shows a reentrant behavior.
