Hermitian and non-Hermitian Weyl physics in synthetic three-dimensional piezoelectric phononic beams

Recently, the evolution of the Weyl point (WP) caused by the introduction of nonhermiticity into Weyl semimetals has aroused great research interest. We consider elastic flexural wave propagation in a phononic beam containing piezoelectric materials and introduce nonhermiticity through active regula...
