Theory Seminar

Quantum Field Theory and Beyond

Nathan Seiberg (Hosted by Nussinov), Institute for Advanced Study

We will review the status of Quantum Field Theory (QFT) and will present it as "the language of physics." Using examples from string theory and condensed matter physics, we will motivate the fact that the standard framework of QFT should be extended. As specific examples, we will review the phenomena of fractons, which do not seem to fit the standard framework of continuum QFT.  We will then present recent attempts to incorporate fractons in a slightly generalized version of quantum field theory.
