DESCRIPTION:Prof. Sebastian Huber\nThe elastic properties of materials are
  determined by a few material constants such as the Young’s modulus. Usi
 ng super-structures one can effectively change these “constants”. In t
 his way we obtain functionalities such as wave-guiding\, acoustic lensing 
 or programmable failure. I will show how topological band theory\, known f
 rom the description of electrons in solids\, provides us with a powerful d
 esign-principle for such mechanical metamaterials. Moreover\, mechanical m
 etamaterials offer a powerful platform for the study of fundamentally new 
 phenomena that are hard to observe in other arenas. Here\, I will highligh
 t the first measurement of a quadrupole topological insulator in a silicon
  based metamaterial and the implementation of an axial gauge field in an a
 coustic Weyl system.\n\nBio:\nSebastian is an Assistant Professor at the I
 nstitute for Theoretical Physics at ETH Zurich. After a Diploma and PhD in
  physics at ETH Zurich he moved to the Weizmann Institute of Science for a
  Postdoc after which he came back to Switzerland with the help of an SNSF 
 Professorship. Last year\, Sebastian Huber won an ERC consolidator grant o
 n the topic of topological mechanical metamaterials\, a field which tries 
 to bridge recent advances in theoretical quantum condensed matter physics 
 and materials design.
