Beyond no-go theorem' Weyl phonons

By using \emph{ab initio} calculations and symmetry analysis, we define a new class of Weyl phonons, i.e., isolated Weyl phonons (IWPs), which are characterized by Chern number $\pm$2 or $\pm$4 in their acoustic phononic spectra and protected by the time inversion symmetry and point group symmetries...
