Mixed Anomaly and Global Consistency

Yuya Tanizaki (RIKEN BNL Research Center)

Symmetry and topology are powerful tools to study strongly interacting dynamics. In this talk, we will see that mixed 't Hooft anomaly and global consistency strongly constrains the possible low-energy dynamics in a simple quantum mechanical example. I will briefly explain the same idea is useful to study the phase diagram of bifundamental gauge theories at finite $\theta$ angles.
