Abstract: It is widely appreciated that symmetry is an important organizing principle of nature. In this talk, I will discuss situations where symmetry can lead to even more surprising consequences that have been largely overlooked before. In particular, taking Kitaev spin-S models as examples, I will argue that certain symmetry there can force the system to realize exotic quantum matter, and such exotic quantum matter is robust even if this symmetry is slightly broken. This idea of symmetry-enforced exotic quantum matter sheds novel insights on the understanding of strongly correlated systems and the realization of exotic quantum matter. If time allows, I will also briefly review some of my previous work that addresses multiple condensed matter problems using a systematic powerful framework based on quantum anomalies, which are ultimately of the same spirit as the analysis of the Kitaev spin-S models.
