Please circulate --- Next seminar will be next Thursday (Nov 2). We skip our seminar this week to avoid the conflict with the ongoing important events: (1) Mathematics in Science: Perspectives and Prospects (10/27-10/28) (2) Kickoff Workshop for the Simons Collaboration on Celestial Holography (10/26-10/29).

For this purpose, one should be able to not only describe the quantum phases using some effective field theories, but also capture the important microscopic information of the material via mathematical formulation. In this talk, I will present a framework to classify quantum phases in quantum materials, where the microscopic information of a material is encoded in its quantum anomaly. I will talk about the application of this framework to classify various exotic quantum phases of matter in different lattice systems. Using our framework, we have obtained many results unexpected from the previous literature. -------- Subscribe to Harvard CMSA Quantum Matter and other seminar videos (more to be uploaded): https://www.youtube.com/playlist?list=PL0NRmB0fnLJQAnYwkpt9PN2PBKx4rvdup Subscribe to Harvard CMSA seminar mailing list: https://forms.gle/1ewa7KeP6BxBuBeRA --- Harvard University CMSA, 20 Garden Street, Cambridge, MA 02138
