DESCRIPTION:Prof. Sebastian Huber\, Condensed Matter Theory and Metamateri
 als group\, Institute for Theoretical Physics\, ETH Zürich\nAbstract:\nTh
 e elastic properties of materials are determined by a few material constan
 ts such as the Young’s modulus. Using super-structures one can effective
 ly change these “constants”. In this way we obtain functionalities suc
 h as wave-guiding\, acoustic lensing or programmable failure. I will show 
 how topological band theory\, known from the description of electrons in s
 olids\, provides us with a powerful design-principle for such mechanical m
 etamaterials. Moreover\, mechanical metamaterials offer a powerful platfor
 m for the study of fundamentally new phenomena that are hard to observe in
  other arenas. Here\, I will highlight the first measurement of a quadrupo
 le topological insulator in a silicon based metamaterial and the implement
 ation of an axial gauge field in an acoustic Weyl system.\n\nBio:\nSebasti
 an is an Assistant Professor at the Institute for Theoretical Physics at E
 TH Zurich. After a Diploma and PhD in physics at ETH Zurich he moved to th
 e 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 on the topic of topological mechanical
  metamaterials\, a field which tries to bridge recent advances in theoreti
 cal quantum condensed matter physics and materials design.
