      Lera, Natalia; Torrent, Daniel; San-Jose, Pablo; Christensen, J.; Álvarez, J. V. American Physical Society (2019)
      We report the finding of the analogous valley Hall effect in phononic systems arising from mirror symmetry breaking, in addition to spatial inversion symmetry breaking. We study topological phases of plates and spring-mass ...
