• openAccess   Mechanical Analogue of a Majorana Bound State 

      Chen, Chun‐Wei; Lera, Natalia; Chaunsali, Rajesh; Torrent, Daniel; Álvarez, J. V.; Yang, Jinkyu; San‐José, Pablo; Christensen, Johan Wiley (2019)
      The discovery of topologically nontrivial electronic systems has opened a new age in condensed matter research. From topological insulators to topological superconductors and Weyl semimetals, it is now understood that some ...
    • openAccess   Valley Hall phases in kagome lattices 

      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 ...
